Large radionuclides emit an alpha particle rather than other combinations of nucleons because the alpha particle...

Large radionuclides 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

Needed masses: ²³⁵U : 235.0439 u, ²³²Th: 232.0381 u, ²³¹Th: 231.0363 u, ²³⁰Th: 230.0331 u, ³He: 3.0160 u, ⁴He: 4.0026 u, ⁵He: 5.0122 u
