Abstract
High-spin states of the 42Ca nucleus, populated in the 68 MeV 18O + 30Si reaction, have been studied in a $\gamma$- $\gamma$-recoil coincidence experiment. The level scheme of 42Ca has been extended up to 13.7  MeV. An elaborate decay pattern with various paths, together with high-quality DCO and polarization information assigns spins and parities for almost all observed levels. The sequence of non-yrast positive-parity states is discussed and compared with highly deformed bands in 36Ar and 40Ca.
