Abstract

The β decay of P35 to levels of S35 has been studied with a large-volume Ge(Li) detector and a gas-flow proportional counter. The P35 was produced via the Cl37(t,αp)P35 reaction by bombardment of NaCl and LiCl targets with 16-MeV tritons, and was chemically separated by conversion to phosphate ion and adsorption on a selective polyvalent anion exchanger. The half-life was measured to be 47.4 ± 0.8 sec. Only one γ transition was observed, at 1572.2 ± 0.4 keV. The P35 decays 997+10% (logft=4.1±0.1) to the 1572-keV 12+ first excited level of S35 and <9% (logft>6.1) to the 32+ ground state, whence its spin-parity is deduced to be 12+. Less than 0.45% of the β transitions proceed to any of the other known S35 levels. The results are compared with the predictions of a recent shell-model treatment.
