Abstract
The nucleus 35Cl has been studied using the reaction 32S( alpha ,p gamma )35Cl. Proton-gamma ray angular correlations have been measured using an E/DE telescope to detect the protons. Gamma ray linear polarizations have been measured with a three Ge(Li) Compton polarimeter. The levels at 4348 keV, 5408 keV and 6088 keV have been shown to have spins and parities of 9/2-, 11/2-, and 13/2- respectively. Branching ratios and electromagnetic multipole mixing ratios were also determined. The lifetime of the 5408 keV level was measured to be 400+or-100 fs by the Doppler shift attenuation method and a lifetime of 9.3+or-0.8 ps was obtained by the recoil distance method for the 6088 keV level. Electromagnetic transition strengths were deduced for the decays of these levels and were found to be inconsistent with the levels being interpreted as members of a rotational band based on the 7/2- level at 3163 keV.
