Observation of the scissors mode in the quasicontinuum

A. Schiller, M. Guttormsen, E. Melby +3

The experimental resonance parameters of the pygmy resonance in rare earth nuclei are compared to global parameters of the scissors-mode states. It is argued that the pygmy resonan…

Thermal and electromagnetic properties of 166-Er and 167-Er

E. Melby, M. Guttormsen, J. Rekstad +3

The primary gamma-ray spectra of 166-Er and 167-Er are deduced from the (3-He,alpha gamma) and (3-He,3-He' gamma) reaction, respectively, enabling a simultaneous extraction of the…

Gamma-ray strength function and pygmy resonance in rare earth nuclei

A. Voinov, M. Guttormsen, E. Melby +3

The gamma-ray strength function for gamma energies in the 1-7 MeV region has been measured for 161,162-Dy and 171,172-Yb using the (3-He,alpha gamma) reaction. Various models are t…

Entropy of thermal quasiparticles in nuclei

M. Guttormsen, M. Hjorth-Jensen, E. Melby +3

Information on level density for nuclei with mass numbers A = 20 - 250 is deduced from discrete low-lying levels and neutron resonance data. The odd-mass nuclei exhibit in general…

Level density and thermal properties in rare earth nuclei

A. Schiller, M. Guttormsen, M. Hjorth-Jensen +3

A convergent method to extract the nuclear level density and the gamma-ray strength function from primary gamma-ray spectra has been established. Thermodynamical quantities have be…
