Question

Two lighter nuclei combine to from a comparatively heavier nucleus by the relation given below: $^2_1X+^2_1X=^4_2Y$. The binding energies per nucleon for, $^2_1X$ and $^4_2Y$ are 1.1 MeV and 7.6 MeV respectively. The energy released in the process is ______ MeV.

Answer 1

$\text{Energy released }= \text{Change in B.E.}$

$(7.6 × 4) – [4 × 1.1] = 26 \;MeV$
