Calculate the binding energy of an alpha...

Calculate the binding energy of an alpha particle from the following data:
`mass of _1^1H ` atom` = 1.007825 u`
mass of neutron = 1.008665 u
`mass of _4^2He ` atom` = 4.00260 u`
Take `1 u = 931 MeV c^(-2)`

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
