Abstract
The level density and radiative strength function for 146,147Sm and 163,164Dy have been extracted from primary γ spectra using the Oslo method. As one approaches the closed N = 82 neutron shell, the structures in the level density become more pronounced due to shell effects. The experimental level densities can be used to explore thermodynamic properties of the nucleus within the microcanonical ensemble. Pygmy resonances, which are based on the scissors mode and seen in deformed rare‐earth nuclei, are not observed in near‐spherical 146,147Sm, as expected. Pygmy resonances in 163,164Dy were studied after 3He‐induced reactions and their width was found to be twice as wide as compared to results reported after neutron‐capture reactions.
