If a neutron turns into a proton and the energy of the decay is less than 0.782343 MeV (such as rubidium-87 decaying to strontium-87), the average binding energy per nucleon will actually decrease.
Eğer bir nötron protona dönüşür ve kaybolan enerji  0.782343 MeV (such as rubidium-87 decaying to strontium-87) ise, enerji bağı azalacak demektir .
