摘要: Excitation energies, mean lifetimes, gamma-ray branching ratios, angular correlations and linear polarizations have been measured for levels below 5.3 MeV in 37Cl. The states were populated using the 34S( alpha ,p gamma )37Cl reaction at bombarding energies between 9.0 12.2 MeV. A gamma-gamma coincidence experiment was performed 11.5 to obtain decay scheme. New measurements made following levels: Ex( tau m)Jpi ; 3087 keV (<40 fs) 5/2+; 3105 (48+or-5 ps) 7/2-; 3626 (40+or-20 3/2, 5/2, 7/2+; 3708 (<25 3/2+, 5/2-; 3740 (<20 4011 (31+or-3 9/2-; 4547 (2.7+or-0.6 11/2- 5271 (2.7+or-0.4 13/2-. results are compared with properties of high-spin negative-parity neighbouring nuclei discussed terms recent shell-model calculations.
