Packing Fraction (In Isotopic mass)

Go Packing Fraction in Isotopic mass = ((Atomic Isotopic Mass-Mass Number)*(10^4))/Mass Number

Binding Energy Per Nucleon

Go Binding Energy per Nucleon = (Mass Defect*931.5)/Mass Number

Packing Fraction

Go Packing Fraction = Mass Defect/Mass Number

Mean Life Time

Go Mean Life Time = 1.446*Radioactive Half Life
