Calculate the mass defect and binding energy per nucleon for an alpha particle whose mass is 4.0035 amu. (mass of proton = 1.0073 amu, mass of neutron = 1.0087 amu ).

Text Solution

Verified by Experts

Mass of alpha particle = 4.0035 amu
mass of alpha particle (calculated ) ` = (2xx 1.0073 xx 2 xx 1.0087) = 4.032` amu
Mass defect ` = (4.0032-4.0035) = 0.0285` amu
Binding energy = Mass defect ` xx 931 = 0.0285 xx 971 = 26.5335` MeV
Binding energy per nucleon ` = (26.5335)/(4) = 6.6334` MeV
