Given information
Given the reaction where one of the initial protons is at rest and all final particles have the same velocity. We are asked to show that the threshold energy is which is also equal to three times the magnitude of the Q-value of the reaction.
Step-by-step explanation
Step 1.
The Q-value can be defined as the difference of the total energy of the products from the total energy of the reactants. Given that one of the initial protons is at rest and that all four final particles have the same speed, and as all the products have the same mass they will have the same kinetic energy.
