  • [摘要]:The T=3/2isobaric analog state (IAS) in 53Co is firmly established through a comprehensive measurement of β-delayed γand proton decay of 53Ni. The determined excitation energy of 53Co IAS combined with the mass of 53Co generates a precise mass excess of −38 333.6(27)keVfor the 53Co IAS, which is 70(18)keV lower than the previously adopted value. The new result solves a problem raised by incorrect assignments of the 53Co IAS of unexpected deviation from the isobaric multiplet mass equation (IMME) at A =53, T=3/2.
