Compound and rotational damping in warm deformed rare-earth nuclei.
The gamma decay in the quasicontinuum from selected configurations of the rotational nucleus 163Er has been measured with the EUROBALL array. A new analysis technique has allowed for the first time to directly measure the compound and rotational damping widths Gamma (micro) and Gamma (rot). Values of Gamma (micro) approximately 20 keV and Gamma (rot) approximately 200 keV are obtained in the sp...
متن کاملDamping of rotational and compound states in warm nuclei
The damping widths associated with compound states of rotating deformed nuclei is analyzed by means of the microscopic shell model calculations. Because of the doorway mechanism present in the damped collective rotation, the rotational E2 transitions is characterized by not only the rotational damping width Γrot but also the spreading width Γnpnh of many-particle many-hole shell model states fo...
متن کاملRotational motion in nuclei.
The exploration of nuclear structure over the last quarter century has been a rich experience for those who have had the privilege to participate. As the nucleus has been subjected to more and more penetrating probes, it has continued to reveal unexpected facets and to open new perspectives. The preparation of our talks today has been an occasion for Ben Mottelson and myself to relive the excit...
متن کاملEffective theory for deformed nuclei
Here, I ≥ I0 denotes the angular momentum, A is a constant determined by fit to data, and I0 is the spin of the band head under consideration. Rotational states are the lowestlying excitations in nuclei far away from closed shells. Our understanding of nuclear rotations is based on the groundbreaking work by Bohr and Mottelson [1], its extension within the general collective model [2], and the ...
