The atomic mass of an alpha particles 4....

The atomic mass of an alpha particles 4.002603 amu and that of oxygen is 15.994915 amu. Find the energy required to split up the oxygen - 16 nucleus into 4 alpha particles .

Text Solution

Verified by Experts

`Deltam=m (4He_(2)^(4))-m(O_(8)^(16))`
`=4xx4.002603-15.994915 =0.015497` a.m.u
Hence BE `=Deltamxx931.5 MeV = 14.435 MeV`
