Calculate the average energy required to extract a nucleon from the nucleus of an `alpha ` - particle ,proton and neutron are 4.00150 a.m.u 1.00728 a.m.u and 1.00867 amu respectively .

Text Solution

Verified by Experts

Mass defect , `(Deltam)=2(m_(p)+m_(n))-m_(N)`
`=4.0319 -4.00150`
`=0.0304` a.m.u
Binding energy of `alpha` - particle = `Deltamxx931.5`
`=0.034 xx931.5`
`=28.3MeV`
Average energy required to extract nucleon = `(28.3)/4`
= `7.07 MeV`.
