Abstract
High-spin states of the
42Ca nucleus, populated in the
68 MeV
18O +
30Si reaction, have been studied in a
-
-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.
