Extensions to the yrast decay sequence of the neutron-rich nucleus ${}_{17}^{41}{\mathrm{Cl}}_{24}$ have been established through the analysis of the $\gamma$ deexcitation of fragments produced in deep-inelastic processes which occur when 230 MeV ${}^{36}\mathrm{S}$ ions interact with a target of ${}^{176}\mathrm{Yb}.$ The highly sensitive GASP array of escape-suppressed Ge detectors was used to measure the resulting $\gamma$-ray deexcitations of both projectilelike and targetlike fragments. New excited states in ${}^{41}\mathrm{Cl}$ are observed at 1445 and 2451 keV, thus adding to the two previously known excited states. Comparisons to shell-model calculations have also been made.
