Abstract

Masses of ⁵²Co, ⁵²Co^m, ⁵²Fe, ⁵²Fe^m, and ⁵²Mn have been measured with the JYFLTRAP double Penning trap mass spectrometer. The isobaric multiplet mass equation for the T = 2 quintet at A = 52 has been studied employing the new mass values. No significant breakdown (beyond the level) of the quadratic form of the IMME was observed (). The cubic coefficient was 6.0(32) keV (). The excitation energies for the isomer and the T = 2 isobaric analog state in ⁵²Co have been determined to be 374(13) keV and 2922(13) keV, respectively. The measured mass values for ⁵²Co and ⁵²Co^m are 29(10) keV and 16(15) keV higher, respectively, than obtained in a recent storage-ring experiment, and significantly lower than predicted by extrapolations. Consequently, this has an impact on the proton separation energies for ⁵²Co and ⁵³Ni relevant for the astrophysical rapid proton capture process. The Q value for the proton decay from the isomer in ⁵³Co has been determined with an unprecedented precision, keV.
