Simple energy release question

This is much larger than the rest energy of the particles, so when they annihilate, a lot of extra energy is released, including a lot of photons.In summary, annihilation of proton-antiproton at rest releases 1.88 GeV energy. However, when annihilation occurs at 2 GeV, it releases more energy and photons due to the higher kinetic energy of the particles in the center of momentum system.

Simple energy release question...

I've recently checked out a fermilab link which says proton-antiproton annihilation at rest releases only 1.88 GeV energy, but compare this to annihilation at 2 GeV, it releases far far more energy and also "MORE PHOTONS"...WHY?

They mean that the p and anti=p each have 2GeV kinetic energy, so the total energy in the center of momentum system is about 6 GeV.
 

What is a simple energy release question?

A simple energy release question is a type of scientific question that focuses on the transfer of energy from one form to another. It typically involves asking how energy is released or transformed in a specific situation or process.

What are some examples of simple energy release questions?

Some examples of simple energy release questions include: How is heat energy released during a chemical reaction? What are the different forms of energy released during a nuclear reaction? How is kinetic energy released when an object falls from a height?

Why are simple energy release questions important to study?

Studying simple energy release questions allows scientists to better understand the fundamental principles of energy and how it impacts various natural processes and phenomena. It also has practical applications in fields such as renewable energy, engineering, and environmental science.

What are some key concepts to understand when discussing simple energy release questions?

Some key concepts to understand when discussing simple energy release questions include energy conservation, energy transfer, and energy transformation. It is also important to have a basic understanding of different forms of energy, such as thermal, kinetic, potential, and electromagnetic energy.

How can simple energy release questions be applied in real-world situations?

Simple energy release questions can be applied in various real-world situations, such as understanding the energy sources and processes involved in electricity production, evaluating the environmental impacts of energy use, and designing more efficient energy systems. They can also be used to explain natural phenomena, such as volcanic eruptions or the movement of tectonic plates.
