Chapter 6: Q21E (page 1520)

If a 危+at rest decays into a proton and a 蟺掳, what is the total kinetic energy of the decay products?

Short Answer

Expert verified

The total kinetic energy of the decay products is 115.7MeV.

Step by step solution

01

State Principle of conservation of energy in the decay process

Energy in the decay process is always conserved. Energy can not be destroyed. It can change forms, but the total amount always remains the same.

02

Calculate the kinetic energy of decay products

The 危+particle decays into meson 蟺0and proton.

The 危掳is initially at rest, so all of its energy is in the form of its rest energy.

  • Rest energy of 危ais, localid="1667801562408" E危+=1189MeV
  • Rest energy of 蟺掳is, localid="1667801582728" E蟺o-135MeV
  • Rest energy of 蚁is E蚁=938.3MeV

From the conservation of energy,

localid="1667801599078" E危+=E伪v+E蚁+KK=1189MeV-135MeV-938.3MeVK=115.7MeV

Therefore, The total kinetic energy of the decay products is115.7MeV.
