“…The lack of similar transitions at higher spins may reflect the different influences of the aligned protons on the nuclear shape, and hence, the wavefunctions. In addition to the results of [7], a few B(MI,I-*I-1) and B(E2,I--*I-1) rates can be determined from the measured lifetimes and mixing ratios [7,14,15]. There are two different mixing ratios reported [14,15] for the 286 keV transition, decaying from the 7/2-state, and the transition rates corresponding to both are given.…”

“…3. Here, the DCO ratios of transitions with known multipolarities in 83y, 83Zr ' 84Zr and S~ [5,14,15] populated in this work are plotted versus the respective initial spin. It is found that by gating on a known coincident stretched E2 transition, a quadrupole transition would produce Roco = 1.1, while a stretched 5oo0-GATE:I)0keV N3 ~., …”

“…1. The curves show the mass gated distribution of ),-ray yields for known transitions, in 83y, 83Zr and 83Nb [5,14,15,23] as a function of energy loss, AE. By setting gates in the mass gated AE spectrum and carefully subtracting 83y and a3Nb, a spectrum of 83Zr with many new transitions is obtained, shown in the middle portion of Fig.…”

“…Recent in-beam experiments [14,15] [14] indicate that the negative parity wave functions contain several fp-shell admixtures; the [303] 5/2 band shows a relatively strong signature splitting implying some mixing with K= 3/2 and K= 1/2 wavefunctions. These calculations also indicate that the [422] 5/ 2 + band is built on a y-soft deformation evolving into a well defined triaxial shape above the first band crossing.…”

The band structure of 83Zr has been investigated using the Daresbury recoil separator and TESSA array with 20 Compton suppressed Ge detectors and the reaction 2SSi(SSNi, 2pn) at 195 MeV. DCO ratios have been used to make many new spin assignments. The three known rotational bands have been extended up to the onset of the five quasiparticle bands. On the basis of the 21/2 +, 23/2 + and 25/2 + yrast and yrare states, a (3qp) structure similar to those found in the isotones 79Kr and S~Sr has been identified. Additional bands have been observed for the first time, one of which appears to be non-collective. Strong mixing between the various negative parity bands is evident. A multiplet of states feeding the three quasiparticle region of the negative parity yrast band has been found. The data is interpreted in the framework of the cranked shell model.

The neutron deficient nucleus S2Zr has been studied through the reaction SSNi(2*Si, 2 p 2 n)82Zr with a calculated cross section of 0.3% of the total fusion cross section at E(2ssi)= 128 MeV. Gamma rays from excited states of S2Zr were measured and identified using the NORDBALL escape-suppression array at the Niels Bohr Institute. Reaction channel selection was performed by use of neutron and charged particle detector arrays in conjunction with the germanium detectors. A rotational band in 82Zr has been identified with spins up to 20 h by analysis of reaction channel selected 7-7 coincidence matrices. Band crossings were identified at frequencies 0.57 and 0.69 MeV.

Deformation parameters of the positive parity yrast band and negative parity bands in S3Zr are deduced from lifetimes and E2/M1 mixing ratios. Lifetimes of high spin states have been determined from recoil distance Doppler shift and Doppler shift attenuation measurements using the S4Fe(32S, 2pn7) S3Zr reaction. Ten lifetimes and five lifetimes limits were determined. The positive parity band, built on the g9/2 K = 5/2 orbital has an average deformation [/~2[ =0.28(2), and shows a reduction of E2 transition strengths in the observed backbend region at I~g21/2 +. In contrast, the E2 strengths in the negative parity states show a steady increase up to U= 15/2-. These states are more strongly deformed than the positive parity states ([/~21=0.33(3)). The E2/M1 mixing ratios show that the negative parity band has K = 3/2 and is prolate, and favour oblate deformation for the positive parity yrast band. In the K= 1/2-band the E2 strength of the 7/2---*3/2-transition yields a deformation I/~zl = 0.26(5). The band structure is compared with calculations within the Hartree-Fock Bogoliubov cranking model.
