Fusion reaction Definition and 29 Threads

An antiproton cannot be used to practically catalyse fusion because the annihilation cross-section between it and a reactant nuclei is greater than the fusion cross-section between the reactant nuclei [1]. Can a positron bound to the antiproton reduce the annihilation cross-section adequately to...

Hello I would like to ask here because I couldn't find an answer anywhere on the internet. I recently noticed that two fusion equations have a very good reciprocal cycle, namely the equation: 1H + 2H = 3He, and the equation 3He + 2H = 4He + 1H. I understand that it may have practical...

Me again! For a sci-fi story I'm working on, I've created a sci-fi technology called an Aneutronic Triple Alpha Fusion Reactor. It works via aneutronic fusion, in this case, fusing Deuterium with Helium 3, but it also mimics the triple alpha process found within stars to maximise fuel use...

In Britannica's article on nuclear fusion, I came across the following description of the recycle of triton and neutrons: What puzzle me are why the tritons are produced from the D-T fusion reaction, given that the products are alpha particle, neutron, and energy; and how the neutrons can be...

Hello! I have finished high school quite a few years ago. I did a physics course that went over nuclear fusion and fission, and I quite enjoyed it. However, I unfortunately no longer have those textbooks (I sold them on as many people do). Now I am doing a bit of programming in the field of...

Can fusion reaction propagate inside a (very thick walled) cappilary if fusion has been initiated at one end? In this situation it seems like all the energy would have nowhere to go but into heating and pressurizing the fuel, providing conditions for further reaction. I imagine this is a...

Video Link According to the video in the link above the binding energy for deuterium is about 2 MeV and the binding energy for tritium is about 8 MeV so the total for the input items is 10 MeV the binding energy for helium is 28 MeV I am confused by this part if the resulting binding energy is...

Homework Statement In the following fusion reaction, a deuterium nucleus (D) combines with a tritium nucleus (T) to form a helium nucleus (He-4). If the following masses of deuterium and tritium are used to produce energy, calculate the total amount of energy produced. Homework Equations E =...

Just read an article about a discovery of the smallest/least massive star in the Milky Way galaxy. The star has 85 times the mass of Jupiter and is known as EBLM J0555-57Ab located about 600 light-years from Earth. The entire article here -...

Hello. Where is come from the heat (about 17,59MeV) from reaction deuteron + tritium -> Alfa + netron + Q although sum of substrates's mass is greater than sum of products's mass?

Good evening, I am new to this forum and do not have a strong physics background. So if my questions seem woefully inept please respond with a simple laymans answer. I understand that there are 2 basic ideas for fusion containment, and that the main 2 components of any successful fusion...

Usually people talk about magnetic confinement schemes or some such thing for fusion reactions presumably because the pressure and temperatures would vaporize/destroy all conceived material vessels too quickly. I would like to hear someone talk about the limits of materials in this realm. So...

[Moderator note: Thread moved from technical section, thus no template is shown] Hi everyone! I'm currently learning nuclear physics and I have a question: Watching the binding energy per nucleon curve, is the following reaction energetically favorable? 2H + 4He -> 6Li And why? Thanks!

Homework Statement In a particular nuclear reaction, a neutron moving at 3.6×105ms−1 has a 70% chance of initiating a nuclear fusion reaction. Which of the following options is a possible probability of a neutron moving at 2.2×105ms−1 initiating the same nuclear reaction? I wouldn't be asking...

I have a question about direct energy conversion; if I want to directly extract electrical energy from the fusion reaction p+Li-7 reaction which generates He nuclei, with a kinetic energy of 8 MeV, what is the most suitable method of doing that? Should some method with charge separation be used...

What type of fusion reaction generates the most neutrons? All I've been able to find information for is D-D fusion and D-T fusion.

How much mass is lost in a single D + T= 4He fusion reaction? And is all of the mass lost converted to energy or just some? The mass lost can be converted to energy using e=mc2.

Hello, I'm trying to figure out how to calculate how much energy is being released in a nuclear fusion reaction from x rays. I think it will have to do with how much deuterium is in the vacuum chamber, how many volts I am using and the amount of resistance of the mesh the electricity is...

Would it be possible to produce a fusion reaction(fusing deterium atoms) using x rays instead of high voltages? Scientist are trying to create fusion using laser, which is just focused photons, but if you have energetic photons such as x rays, which would knock the electron of the deterium atom...

Homework Statement In a fusion reaction, the nuclei of two atoms join to form a single atom of a different element. In such a reaction, a fraction of the rest energy of the original atoms is converted to kinetic energy of the reaction products. A fusion reaction that occurs in the Sun converts...

why it is so difficult for scientist to control the fusion reaction why they not make a lage room with heat resistance walls and make a explosion to start the fusion reaction and add appropiate amount of hydogen by some hole if small quantity of hydrogen is entered in such room so the...

I'm currently studying Freidberg's plasma physics and fusion energy book, I've heard that Fusion between Deutrium and tritium is most suitable for a fusion reactor and how columb barrier plays its role....my question is what happens when two neutrons fuse together? do they face columb collision?

Homework Statement In a fusion reaction, the nuclei of two atoms join to form a single atom of a different element. In such a reaction, a fraction of the rest energy of the original atoms is converted to kinetic energy of the reaction products. A fusion reaction that occurs in the Sun converts...

ala the sun? Jupiter's upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium http://en.wikipedia.org/wiki/Jupiter considering many nuclear weapons have a fusion stage would the explosion propogate? what would rain on my parade?

In a fusion reaction, the nuclei of two atoms join to form a single atom of a different element. In such a reaction, a fraction of the rest energy of the original atoms is converted to kinetic energy of the reaction products. A fusion reaction that occurs in the Sun converts hydrogen to helium...

Homework Statement Consider the following fusion reaction 2H+3H →4He + n in which deuterium and tritium fuse together to form a stable isotope of helium plus a neutron. In all of physics, we see experimental confirmation of Conservation of Energy, in which the total amount of energy in a closed...

Homework Statement One of the thermonuclear or fusion reactions that takes place inside a star such as our Sun is the production of helium-3 (3He, with two protons and one neutron) and a gamma ray (high-energy photon, denoted by the lowercase Greek letter gamma, ) in a collision between a...
