Measurement of Conversion Coefficients in Normal and Triaxial Strongly Deformed Bands in ¹⁶⁷Lu

Quadrupole Moment Measurements of TSD1 and TSD2 Bands in 167Lu

The triaxial strongly deformed (TSD) bands in 167Lu were populated by the 123Sb(48Ca, 4n) reaction with a beam energy of 203 MeV. Gamma rays, requiring five fold or more in prompt coincidence, were detected with the Gammasphere spectrometer. Of particular interests are TSD bands 1 and 2 which have previously been interpreted as zero phonon and one phonon wobbling bands, respectively. Using the ...

Beyond band termination in 157Er and the search for wobbling excitations in strongly deformed 174Hf

High-spin terminating bands in heavy nuclei were first identified in nuclei around Er90. While examples of special terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work the high-spin structure of 157Er has been studied using the Gammasphere spectrometer. The subject of triaxial superdef...

Nuclear magnetic dipole properties and the triaxial deformation

Nuclear magnetic dipole properties of ground bands and γ-vibrational bands are studied for the first time using the triaxial projected shell model approach. The study is carried out for the Dy and Er isotopic chains, ranging from transitional to well-deformed region. It is found that the g-factor ratio of the 2 state in ground bands to that of γ-bands, r = g(2, γ-vib)/g(2, ground), varies along...
