Observation of a strong correlation between g (2 + γvib) and g (2 + rot) in strongly deformed nuclei

摘要: The E2/M1 multipole mixing parameters of cascade transitions in γ-vibrational bands 154Gd, 166Er and 168Er have been determined by γ -@#@ directional correlation measurements as: \(\delta \left( {{}^{154}{\text{Gd}}\left( {3_\gamma ^ + \to 2_\gamma } \right)} \right) = - 4.3_{ 2.1}^{ 9.4}\) {{}^{166}{\text{Er}}\left( {5_\gamma 4_\gamma 1.94_{ 0.21}^{ 0.23}\) (with conversion data [15] taken into account) These were used to derive g(2+γvib) − g(2+ rot). results, together with g-factors derived from direct IPAC Mossbuer spectroscopy [10] or use transient fields [9, 31] exhibit a strong between both g-factors, i.e. if rot) is large γvib) small vice versa. most simple interpretation the assumption more less different density distribution protons neutrons nuclei.
