Abstract
The nuclear level density and the -ray strength function have been determined for in the energy range up to 2 MeV below the neutron separation energy using the Oslo method with the reaction. A comparison to shows that the level density of is smaller by an approximately constant factor of two. This behavior is well reproduced in a microscopic, combinatorial model calculation. The -ray strength function increases at low -ray energies, a feature which has been observed in several nuclei but which still awaits theoretical explanation.
