[en] The γ-ray decays of high-spin states in ^3536637Cl and ³⁷Ar were studied via heavy-ion-induced reactions involving ¹⁴N and ¹⁸O bombardment of targets of ²⁴²⁶Mg and ²⁷Al. Decay schemes and spin-parity assignments were deduced from γγ-coincidence measurements, γ-ray angular distribution and linear polarization measurements, and recoil-distance lifetime measurements. The observed levels are compared to predictions of the weak-coupling model. It is concluded that all the observed high-spin states can be assigned to configurations based on one- or two-nucleon excitations from the (2s, 1d) shell into the (1f, 1p) shell, and that not all the energetically available yrast levels of these configurations have, as yet, been found
