Find the binding energy of an alpha-part...

Find the binding energy of an `alpha`-particle from the following data.
Mass of helium nulceus `=4.001235 am u`
Mass of proton `=1.007277 am u`
Mass of neutron `=1.00866 am u`
(take 1 amu=`931.4813 MeV)`.

Text Solution

Verified by Experts

`alpha ` - particle consists of 2 protons and 2 neutrons Mass Defect , `Delta m=(Zm_(p) +Nm _(n) -M(""_(2)^(4)H )`
` =2xx1.007277+xx1.008666-4.001265`
`=0.3062U `
Binding energy `=Delta mxx931.4813 MeV`
`=0.03062xx931.48=28.52` Me V
