Find the energy required to split `._(8)^(16)O` nucleus into for `alpha` - particles. The mass of `alpha`- particle is `4.002603u` and that of oxygen is `15.994915 u`.

Text Solution

Verified by Experts

Mass of `alpha`- particle `= 4.002603u`
Mass of oxygen ` = 15.9949 15 u`
BE= [Mass of `4 alpha` - particles - mass of oxygen] x `931.5MeV`
`B.E =[4 xx 4.002603- 15.994915] x 931.5 MeV`
` = (16.01412-15.9994915) x 931.5 MeV`
`=0.015497 x 921.5 MeV,`
`B.E=14.43 MeV`
