Revalidation of the isobaric multiplet mass equation at A=53, T=3/2

Physics Letters B, 2016
The T=3/2 isobaric analog state (IAS) in 53Co is firmly established through a comprehensive measurement of β-delayed γ and proton decay of 53Ni. The determined excitation energy of 53Co IAS combined with the mass of 53Co generates a precise mass excess ...
