Spectroscopy of /sup 87,88,89/Sr with (n,. gamma. ) and (d,p) reactions [electronic resource]
Over the recent years the nuclear structure around the N = 50 shell closure, which is very pronounced in the strontium and zirconium isotopes, has been the subject of extensive experimental and theoretical work. On the proton side Z = 38 and Z = 40 provide fairly closed sub-shells. In the strontium...

| 520 | 3 | |a Over the recent years the nuclear structure around the N = 50 shell closure, which is very pronounced in the strontium and zirconium isotopes, has been the subject of extensive experimental and theoretical work. On the proton side Z = 38 and Z = 40 provide fairly closed sub-shells. In the strontium isotopes the lg₉₂ neutron shell is closed at ⁸⁸Sr, supplying relatively pure neutron-hole and neutron-particle states with large spectroscopic factors in ⁸⁷Sr and ⁸⁹Sr, as well as core-coupled states. The mass region is thus ideally suited to examine the transition from a correlated to an uncorrelated (chaotic.) excitational behavior. These two types are characterized e.g. by the density of excited states, the transition strengths, and the spectroscopic factors observed in transfer reactions. We conducted (n,..gamma..) and (d,p) reactions leading to /sup 87,88,89/Sr in addition to ⁸⁸Sr(d,t)⁸⁷Sr and 24 keV neutron capture in ⁸⁸Sr. The vast amounts of data were used to analyze the level densities and transition strengths in the statistical model. Correlations were found between the selective population of states dominating the (d,p) process, and the statistical decay of the compound state formed after thermal neutron capture. In the course of the analyses we established essentially complete level schemes (within limited spin windows centered around the spin of the capture state) up to around half the neutron binding energy. The E1 partial decay widths were found to agree with results of giant resonance calculations. We intend to give an overview of the experiments and outline the results of the model calculations. 24 refs., 4 figs. | |
