Calculate the binding energy of an a-particle if rest mass of a is `"_(2)^(4)He = 4.002603` amu.

Text Solution

Verified by Experts

The `alpha`-particle is a helium nucleus consisting of two protons and two neutrons.
Mass of 1 proton = 1.007277 amu
Mass of 1 neutron = 1.008655 amu
Mass of a helium nucleus = 4.002603 amu
`therefore E_(b)` = binding energy
`=[Zm_(p) + Nm_(a) - M_(A)] xx 931 MeV`
`=[2 xx 1.007277 + 2 xx 1.008655- 4.002603] xx 931 MeV`
`=[2.01455 + 2.01731 - 4.002603] xx 931 MeV`
[The mass of the electrons in the helium atom is neglected here]
