Neutrons Definition and 224 Threads

I was just reading this.. Free Neutron decays into proton, electron and neutrino. neutron --> proton + electron + v (neutrino) ---- My Question: Neutron is chargeless. How can it give proton and neutron which are charged ? (If the question is simple i am sorry, I am new to nuclear physics)

Hey, I was wondering about possible interaction with free neutrons and if any have been seen experimentally. Here is a quote from hyperphysics: 'A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus.' Can a photon interact with the...

I have been having an https://www.physicsforums.com/showthread.php?t=145867&page=3" with Morbius on the Nuclear Engineering board about whether the energy released in fission is from the nuclear force or the coulomb force. This quote from Feynman suggests that the energy is from the coulomb...

free neutrons are unstable: would a muon in say uranium be "stable"? free neutrons are unstable: would a muon in say uranium be "stable"? free neutrons decompose and have a half-life of about 15 minutes. neutrons bound in a nucleus, especially in a magic shell configuration like helium-4 or...

Hi! Long time reader first time writer here. Just wondering, how can a neutronstar that only consists of neutrons be abel to generate an magnetic field and become an pulsar? If I hasn´t got it wrong a pulsar can work in different ways either its momenthum can be resposable for the light...

Protons + Neutrons + Electrons =? This question has been boggling my mind for some time, hopefully some of you can shed some light on the subject. What would happen if one were to shoot a beam of Protons, a beam of neutrons, and a beam of electrons next to each other? I've made a little diagram...

thanks hootenanny:wink: im not sure if my teacher had set this question wrongly or not? because I am finding it hard to answer. the question goes: TWO statement below are INCORRECT. which are these 2 statements? A.) the nucleus of an atom contains only neutrons and protons. B.)The...

Why do gases absorb neutrons less readily than water? Any ideas on the above question? Leila

If not why not?

Hi to all, I have two questions concerning neutrons. How is it possible to accelerate neutrons? Since they have no charge, it shouldn't be possible by applying an electric field. I read somewhere that it should work by using a magnetic field. Can somebody explain how that is working? I mean...

I was wondering that if neutrons stablize that atomic nuclei then it should stablize other systems. Or can other particles be stablized by the proton,electron or neutron?

This might be a dumb question, but in all my years of chemistry and physics studies I have never gotten an explanation of where electrons and protons get their charges from. I don't know if this is the right forum, maybe one of the physics forums might be better? Maybe a physical chemist can...

How does adding neutrons to an atom change the atom?

Their spin quantum numbers are 1/2 and -1/2. How to explain these in terms of quarks?

Electrons, Photons Neutrons,,,,, Electrons and photons are used in all forms of technology, are any of the other particles used in technology and if so an eg of where? Other than nuclear fission and particle accelertors where else do neutrons come into play?

Hello. I have a few questions to ask you guys. First, what is the purpose of neutrons in an atom? What would happen if all the neutrons in the atom were spontaneously stripped away? Also, what would happen if all the electrons in an atom were spontaneously stripped away?

how does binding energy decreases with addition of nuetron

Neutrons and protons consist of quarks right? my question is ;has anyone theory as to how are they aranged inside of protons/neutrons?. one orbits another or whatever?

A long time ago, when I did my degree I was taught that Neutrons have a half life of (about 10 minutes?). I also remember that the elementry particle equation was: N <-> P+e. Now, a proton plus an electron could look a lot like a hydrogen atom and I also remember that the electron in a...

Hey guys, posted this in HW help, but its actually just a thought i had in chem class. I was wondering if light or heavy elements would be better at stopping slow moving neutrons? And how come? By heavy and light, i mean mass. Heres what i think. I thought a heavy element would have a...

Hey guys, I was wondering if light or heavy elements would be better at stopping slow moving neutrons? And how come? By heavy and light, i mean mass. I always thought a heavy element would have a better chance of stopping particles because they have a high probability of smacking the...

We all know that the helium nucleus is very stable because it consists of two protons and two neutrons. My question is why aren't we seeing 4 neutrons sticking together forming an even more stable nuclide, since neutrons exert only the strong attractive nuclear force but not the repulsive...

A beam of 6.61MeV protons is incident on a tanget of 2713Al. Those that collide produce the reaction p + 2713Al ---> 2714Si + n (2714Si has a mass of 26.986721amu.) Neglect any recoil of the product nucleous and determine the kinetic energy of the emerging neutrons. Okay, what the...

dear reader, Does anyone know about Quark. i know that quarks make the nutrons and protons. But i still don't understand it clearly. Benzun
