    please answer 11 and 12 because they are connected to the same information given The Proton would decay to a neutral Pion and a Positron, there are no additional or missing particles. Both the Pion and the Positron are relativistic even when the initial Proton is at rest. Assume that the Proton starts at rest. The Proton has a rest mass of 938 MeV/c the neutral Pion has a rest mass of 135 MeV/c and the Positron has a rest...

    1. A neutral pion with rest energy 135 MeV and total energy 300 Me V is traveling in the +z direction. It decays into two massless phoons ( π + γ), which happens to go in the +z and-z directions write out the energy and momentum equations and determine the momentum and wavelength of each photon.

    The centre of mass, or centre of momentum, (CMS) frame is that in which the sum of the momenta (i.e., the total momentum) of all particles is zero. An electron has a kinetic energy K of 1 MeV and is incident on a proton at rest in the laboratory. The goal of this exercise is to calculate the speed of the CMS frame moving relative to the laboratory. (a) Express the initial energies Ee, Ep and initial momenta pe, pp...

    A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...
