1. The problem statement, all variables and given/known data The nuclear masses of parent and daughter nuclei are Mp= 226.025 amu and Md=222.017 amu.Mass of alpha particle is Mα=4.002amu.Find qvalue and kinetic energy of alpha particle emitted for the alpha decay. 2. Relevant equations Q=(Mp -Md-Mα)amu...1 Assuming nucleus to be at rest as it is very heavy Q=Eα(1+ Mα/Md)...2 3. The attempt at a solution Putting given values in 1 i get Q=5.589MeV (1amu= 931.5MeV) Substituting this in 2 i get Eα=5.490 MeV. Have i done this correctly??
