Atoms And Nuclei

A common example of alpha decay is \({ }_{92}^{238} \mathrm{U} \longrightarrow{ }_{90}^{234} \mathrm{Th}+{ }_{2} \mathrm{He}^{4}+\mathrm{Q}\)

Given :

\({ }_{92}^{238} \mathrm{U}=238.05060 ~\mathrm{u}\),

\({ }_{90}^{234} \mathrm{Th}=234.04360 ~\mathrm{u}\),

\({ }_{2}^{4} \mathrm{He}=4.00260 ~\mathrm{u}\) and

\(1 \mathrm{u}=931.5 \frac{\mathrm{MeV}}{c^{2}}\)

The energy released \((Q)\) during the alpha decay of \({ }_{92}^{238} \mathrm{U}\) is __________ MeV
