- Theoretical (qualitative) prediction of exothermic (with the release of energy) nuclear reaction, in fusing together two light nuclei to form a heavier nucleus and in splitting heavy nucleus to form middle order (lower mass number) nuclei, is evident from the shape of BE per nucleon versus mass number graph. Also, calculate the disintegration energy Q for a heavy nucleus (A = 240) with BE/A ∼ 7.6 MeV per nucleon split into two equal halves with A = 120 each and BE/A ∼ 8.5 MeV/nucleon; Q ∼ 200 MeV.
