Abstract

${}^{36}K$ was produced via the ${}^{36}{Ar} (p, n) {}^{36}K$ reaction. Measurement of $27 β^{+}$ delayed $γ$ rays associated with the decay of ${}^{36}K$ implied 10 new $β^{+}$ branches to energy levels in ${}^{36}{Ar}$ . Branching ratios and $log ft$ values are calculated for the $β^{+}$ branches. Restrictions on spin and parity assignments for the ${}^{36}{Ar}$ levels are given, as well as branching ratios for $γ$ transitions from these levels. The half-life of ${}^{36}K$ is determined to be 344 ± 3 msec.

RADIOACTIVITY ${}^{36}K$ [from ${}^{36}{Ar} (p, n)$ , $E = 18$ MeV]; measured $E_{γ}$ , $I_{γ}$ , $τ_{\frac{1}{2}}$ ; deduced $β^{+}$ branching ratios, $log f t' s$ , ${}^{36}{Ar}$ levels $l^{π}$ ; enriched targets.
