दिया है: 26Fe56 के लिए - प्रोटॉनों की संख्या Z = 26

न्यूट्रॉनों की संख्या (A - Z) = 56 - 26 = 30

mp = 1.007825 amu

mp = 1.008665 amu

m = 55.934939 amu

∆m = [Z mp + (A - Z)mn] - m

= [26 x 1.007825 + 30 x 1.008665] -55.934939

∆m = 0.528461 amu

∴ बंधन ऊर्जा

∆E = 0.528461 x 931 MeV

= 491.997191 MeV

∴ बंधन ऊर्जा प्रति न्यूक्लियॉन

Eb\(\frac{\triangle E}{A} = \frac{491:9971}{56}\)

Eb = 8.786 MeV प्रति म्यूक्लियॉन
