Abstract
Excitation energies, mean lifetimes, gamma -ray branching ratios, angular correlations, mixing ratios and linear polarizations have been measured for the first twelve levels of 37Ar using the 34S( alpha ,n gamma )37Ar reaction. Parity assignments were made for the following levels: 3173 keV, 5/2+, 3274 keV, 5/2-, 3527 keV, 7/2-, and 3602 keV, 3/2+ or 5/2-. The spin and parity of the 3707 keV state ( tau m=370+or-95 fs) was determined, Jpi =11/2-. Three new low energy gamma -ray transitions were observed and six new mixing ratios were determined. The authors found that the negative parity levels which decay to the 1611 keV 7/2- state are represented qualitatively by the core excitation model.Keywords
