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 × 10 −8 was achieved. Analysis of th...

| Zusammenfassung: | 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 × 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. |
