Mass measurements of $^{56-57}$Cr and the question of shell reincarnation at $N = 32$
Binding energies determined with high accuracy provide smooth derivatives of the mass surface for analysis of shell and pairing effects. Measurements with the Penning trap mass spectrometer ISOLTRAP at CERN-ISOLDE were made for $^{56-57}$Cr for which an accuracy of $4 \times 10^{-8}$ was achieved. A...

| description | Binding energies determined with high accuracy provide smooth derivatives of the mass surface for analysis of shell and pairing effects. Measurements with the Penning trap mass spectrometer ISOLTRAP at CERN-ISOLDE were made for $^{56-57}$Cr for which an accuracy of $4 \times 10^{-8}$ was achieved. Analysis of the mass surface for the supposed new $N = 32$ shell closure rather indicates a sub-shell closure, but of a different nature than known cases such as $^{94}$Sr. |
