Abstract

The 44Ca(d, α)42K reaction was studied at a bombarding energy of 11 MeV using a broadrange magnetic spectrograph and solid-state detectors. About thirty energy levels were identified in 42K, up to an excitation energy of 3.5 MeV. Excitation functions corresponding to some of the low-lying energy states of 42K were measured in the incident energy range from 10.4 to 11.6 MeV. Angular distributions of the α-particle groups corresponding to the excitation of about twenty energy levels in 42K have been measured. DWBA calculations were performed and L-values for most of the above transitions were deduced. The results were compared with previous information and possible spin and configuration assignments are proposed for some of the states. Centroids of states interpreted as belonging to the (1d 3 2-1)p (1f 7 23)n, (2s 1 2-1)p (1f 7 23)n and the (1d 3 2-1)P (1d 3 2-1 1f 7 24)n configurations were found to be in good agreement with calculations based on the weak-coupling model.
