“…Its spin and parity are deduced in the following way. The 11/2 ~9/2-796keV M1 tran- sitions is identified previously [7], and the corresponding transition in 2~ is the 884keV y-ray. The K-conversion coefficient of the 884keV transition is very, close to the theoretical value [13] for an M1 transition, indicating that this ll/2--+9/2-transition is of almost pure Mt character.…”

Time spectra were recorded between the beam bursts, the separation of which were extended up to 600 ns by a fast pulsing device [101 since one objective was to determine the half-lives of the 21/2 + isomers reported in [6] and [7]. Some time curves of 7-rays in the yrast cascade are presented in Fig.…”

States in 2~176are populated using the reaction 2~176The ~i13/2 single-proton states and all the members of the v(2~-)| rc h9/2 quintuplet are identified in both nuclei. The half-lives of the isomeric J~=21/2 § states in both isotopes are measured and found to be 90_+7ns and 100_6ns, and from these values suggestions for the half-lives of the previously reported J~= 25/2 -~ isomers are made. The structures of the multiplets of the form v(Pb)| are calculated in the framework of the shell model and it is shown that the main features can be derived from the re-v-a effective interaction. The wave functions of the 4~ and 4~ states in /~176 are deduced indirectly from the calculation in 2o3.2OSBi"

“…The energies and intensities of the transitions depopulating iso~ meric states are given in Table 1. The agreement with earlier work [6][7][8] is good for those transitions which were assigned to 2o3, ~OSBi previously. For the search for the low energy isomeric transitions an electron spectrometer consisting of a superconducting solenoid and two high resolution cooled Si(Li) detectors was used [9].…”

“…Experimental information on systems with a few nucleons outside 2~ is therefore of great importance. In previous studies of the high states in 2~ and 2~ the existence of isomers with U=25/2 + was suggested [6,7] but the corresponding isomeric transitions could not be found experimentally and thus only a limit could be given for their excitation energies. Consequently, the energies of all states above the 25/2 + isomers in these nuclei were only deter-* Present address: Institute of Physics, university of Oslo, Oslo, Norway ** Present address: G.S.I., D-6100 Darmstadt, FRG, on leave from Tata Institute of Fundamental Research, Bombay, India *** On leave from Institute of Nuclear Physics, Krakow, Poland mined within those limits and comparisons with theoretical results were uncertain.…”

High spin states in 2~176 populated in the z~176 (~,4n) reactions, have been studied using gamma-ray and conversion-electron spectroscopy. Several previously unobserved isomeric transitions were identified by electron-electron coincidence measurements in both isotopes and in 2~ a new isomer was found. The observed states can be explained as arising from couplings of the odd h9/2 proton to neutron states in the neighbouring Pb cores. Reduced transition probabilities are derived and discussed. ENuclear Reactions: 2~176 (e, 4n), E=50MeV; measured E~,I s, 7(0), e ecoin., T1/2, 2~176 deduced levels, J, ~z, B(E2), e--spectrometers, Si(Li)-, Gedetectors.

High-spin states in 2~populated in the 2~ 4n) reaction with bombarding energies around 50 MeV have been studied using 7-ray spectroscopic techniques. Spins and parities have been assigned on the basis of angular distribution and 7-ray linear polarization measurements. States with spins up to 39/2 + and excitation energies around 6 MeV have been identified. Calculations using the empirical shell model have been performed in order to assign configurations.
