SOLUTION :
mass lost in decay
= mu - mt - m particle
= 232.037146 - 228.02873 - 4.002603
= 0.005813 amu .
= 0.005813 * (1.6 * 10^(-27) ) kg (1 amu = 1.6*10^(-27) kg)
= 9.3008 * 10^(-30) kg
Now, energy released , E
= m c^2
= 9.3008 * 10^(-30) * (3*10^8)^2 (c = speed of light = 3*10^8 m/s)
= 8.37072 * 10^(-13) kg.m/s^2 * m (= N-m = J)
= 8.3702 * 10^(-13) J
= 8.3702 * 10^(-13) / (1.6 * 10^(-19)) ev ( 1 ev = 1.6*10^(-19) J)
= 5.231375 * 10^6
= 5.231375 Mev (ANSWER).

86X212 (atomic mass = 211.99068 u) undergoes decay. Assuming all the released energy is in the form of kinetic energy of the particle (atomic mass = 4.002603 u) and ignoring the recoil of the daughter nucleus (84X1208 atomic mass = 207.98123 u), find the speed of the particle. Ignore relativistic effects. Number Units
A uranium-238 nucleus at rest undergoes radioactive decay, splitting into an alpha particle (helium nucleus) with mass 6.64×10-27 kg and a thorium nucleus with mass 3.89×10-25 kg.

Suppose some nucleus undergoes decay, releasing 5.4 MeV of energy. If the daughter product of this reaction is 93X237 (atomic mass = 237.04816) , it will recoil away as the particle leaves. Determine (a) the energy of the daughter product and (b) the energy of the particle (atomic mass = 4.002603 u). Assume that the energy of each particle is kinetic energy, and ignore any other small amounts of energy that might be carried away by other emissions. In addition,...
