Question: Large radio-nuclides emit an alpha particle rather than other combinations of nucleons because the alpha particle has such a stable, tightly bound structure. To confirm

Large radio-nuclides emit an alpha particle rather than other combinations of nucleons because the alpha particle has such a stable, tightly bound structure. To confirm this statement, calculate the disintegration energies for these hypothetical decay processes and discuss the meaning of your findings:
a. 235U †’ 232Th + 3He
b. 235U †’ 231Th + 4He
c. 235U †’ 230Th + 5He
The needed atomic masses are

232Th 232.0381 u 3He 3.0160 u 2Th 231.0363 He 4.0026 u 230Th 230.0331 He 5.0122 u 2U 235.0429 u
