A Theoretical Account on Beta Decay Stability for Isobaric Family

Nucleides with same mass number but with different atomic number are called isobars. Most of the unstable nucleides are β emitters. The stability of β emitting isobars is predicted from mass parabolas. Using semi empirical formula masses are calculated and mass parabolas are drawn for odd A and Even A isobars. All isobars decays into stable isobar by β+ emission or β- emission or electron capture. This study gives the theoretical account for the beta decay stability against mass parabolas for isobaric family.
