Abstract:

The structure of the N = 20 nucleus 37 Cl has been investigated in the 24 Mg( 16 O , 3 p ) reaction with a 70 MeV 16 O beam. A complex level scheme extended up to an excitation energy of 17 MeV and spins (29 / 2 + )and (27 / 2 − ) on positive and negative parity, respectively, has been established. Lifetimes for the new states have been investigated by the Doppler shift attenuation method. Large-scale shell-model calculations have been performed in a valence space involving orbitals in the sd and fp shells using the sdfp and SDPF-M effective interactions. The comparison with the experimental data indicates the need for slight changes of the sd - fp energy gaps produced by these interactions.
