# Does the decay energy of a beta decaying isotope become lower as the half life becomes greater (or vice versa)?

In other words, does half life have a correlation with decay energy of a beta particle?

• Do you mean the energy of the beta particles?!? – user154997 Oct 20 '17 at 1:13
• Yes, I mean the energy of the beta particles – Aakash Sunkari Oct 20 '17 at 1:14
• @LucJ.Bourhis yes, I mean the energy of the beta particles – Aakash Sunkari Oct 20 '17 at 1:15
• Then no. The decays of past nuclei do not influence the decay of a nucleus in any way: they are all independent from each others. – user154997 Oct 20 '17 at 1:21
