Question

(a) How much energy is required to remove a neutron from 1'N to form 3N? (Hint: Make use of the masses to determine the binding energies. [mass(N 14.003074u; massN)-13.005739u; lu 931.49 MeV/c2] 210Po (mass 209.9829u) alpha-decays to 206Pb (mass 205.9745u). What is the energy of the emitted alpha particles, assuming the 206Pb nucleus is produced in its ground state? How do the values of the atomic mass, A and atomic number, Z change between initial and final state nuclei in alpha-, beta- and gamma-decays, respectively? (b) (c)

Explanation / Answer

Solving 1st question

Change in mass=(13.005739+1.008664)-(14.003074)=0.011329 u

Energy required=0.011329*931.5=10.55 MeV
