The previously unreported decay of ${}_{}{}^{36}{}_{}{}^{}\mathrm{P}$ to levels in ${}_{}{}^{36}{}_{}{}^{}\mathrm{S}$ has been studied from activity generated by the ${}_{}{}^{37}{}_{}{}^{}\mathrm{Cl}$($n$,$2p$)${}_{}{}^{36}{}_{}{}^{}\mathrm{P}$ reaction using neutrons produced through the stopping of 70-MeV deuterons in a Be target. The half-life for ${}_{}{}^{36}{}_{}{}^{}\mathrm{P}$ was measured to be 5.9±0.4 s. From $\gamma$ singles and coincidence measurements excited states in ${}_{}{}^{36}{}_{}{}^{}\mathrm{S}$ at 3290.7($2^{+}$), 4192.7($3^{-}$), and 5830.8($4^{-}$,$5^{-}$) keV were established. The ${}_{}{}^{36}{}_{}{}^{}\mathrm{S}$ levels are compared with results from ($d$,${}_{}{}^3{}_{}{}^{}\mathrm{He}$) and ($t$,$p$) reactions and shell-model calculations, and the nature of the negative-parity states is discussed.
