A nucleus with mass number 220 initially at rest emits an -particle. If the Q value of the reaction is 5.5 MeV, calculate the kinetic energy of the -particle
(a) 4.4 MeV (b) 5.4 MeV
(c) 5.6 MeV (d) 6.5 MeV
Q-value of the reaction is 5.5 eV
By conservation of linear momentum
On solving equation (i) and (ii) we get = 5.4 MeV.
