Maximally aligned states in the proton drip line nucleus Sb-106 (original) (raw)

High-spin states in 106 Sb have been investigated in the 54 Fe(58 Ni, 1α1p1n) reaction by in-beam γ-spectroscopic methods using the EUROBALL detector array equipped with charged particle and neutron detectors. On the basis of measured γ γ-coincidence relations, angular distributions, and linear polarization ratios a significantly extended level scheme has been constructed up to spin and parity I π = (19 −) and E x ∼ 6.5 MeV. The experimental results are interpreted within the framework of the gdsh shell model using a realistic effective nucleon-nucleon interaction. Candidates for states with fully aligned angular momenta in the π(d 5/2 , g 7/2) 1 ν(d 5/2 , g 7/2) 5 valence space are identified at 4338 and 5203 keV, as well as in the π(d 5/2 , g 7/2) 1 ν(d 5/2 , g 7/2) 4 h 1 11/2 space at 6087, 6573 and 6783 keV.
