  • Smooth Termination of Rotational Bands in 62Zn: Evidence for a Loss of Collectivity
  • 1998
  • Ingår i: Physical Review Letters. - 1079-7114. ; 80:12, s. 2558-2561
  • Tidskriftsartikel (refereegranskat)abstract
    • Two sets of strongly coupled rotational bands have been identified in Zn-62. These bands have been observed up to the terminating states of their respective configurations. Lifetime measurements indicate that the transition quadrupole moments in these bands decrease as termination is approached. These results establish the first terminating states of rotational bands in the A similar to 60 mass region and confirm the predicted loss of collectivity associated with smooth band termination.

  • Search for hyperdeformation in Gd-146,Gd-147
  • 1996
  • Ingår i: Physical Review C. Nuclear Physics. - 0556-2813 .- 1089-490X. ; 54:4, s. 1585-1588

    • A search was undertaken to look for evidence of hyperdeformation in Gd-146,Gd-147. Three experiments employing Gammasphere for gamma-ray detection coupled with the Microball for channel selection via charged particle detection were carried out with increasing detection sensitivity and statistics. No definitive evidence for band structures that could be assigned to hyperdeformation could be found. Candidates previously reported are shown not to have properties consistent with a band structure.

  • Observation and Quadrupole Moment Measurement of the First Superdeformed Band in the A~60 Mass Region
  • 1997
  • Ingår i: Physical Review Letters. - 1079-7114. ; 79:7, s. 1233-1236
  • Tidskriftsartikel (refereegranskat)abstract
    • A high-spin rotational cascade of six gamma rays has been observed in Zn-62. The quadrupole moment of 2.7(-0.5)(+0.7) e b measured for this band corresponds to a deformation beta(2) = 0.45(-0.07)(+0.10). The properties of this band are in excellent agreement with calculations that predict high-spin superdeformed bands in Zn-62 with deformations beta(2) = 0.41-0.49. These results establish a new region of superdeformation for nuclei with neutron and proton numbers N, Z approximate to 30-32.

  • Triaxial superdeformed bands in [Formula Presented]
  • 1998
  • Ingår i: Physical Review C - Nuclear Physics. - 0556-2813. ; 57:1, s. 1-5
  • Tidskriftsartikel (refereegranskat)abstract
    • Four new superdeformed bands have been found in the nucleus [Formula Presented]. The good agreement between experiment and configuration-dependent shell correction calculations suggests that three of the bands have triaxial superdeformed shapes. Such unique features in mass [Formula Presented] superdeformed bands have been predicted, but not observed experimentally until now. A fourth band in [Formula Presented] is interesting due to a fairly constant and unusually high dynamic moment of inertia. Possible interpretations of this structure are discussed.
