  • Decay Out of the Doubly Magic Superdeformed Band in the N=Z Nucleus 60Zn
  • 1999
  • In: Physical Review Letters. - 1079-7114. ; 82:17, s. 3400-3403
  • Journal article (peer-reviewed)abstract
    • The doubly magic superdeformed band in the N = Z nucleus Zn-60 has been identified. Linking transitions connecting this band to the yrast line provide the first spin, parity, and excitation energy measurements for superdeformed states in the A similar to 60 region. The stretched-E2 character and relatively large B(E2) values of these transitions suggest a nonstatistical decay-out process.

  • Smooth Termination of Rotational Bands in 62Zn: Evidence for a Loss of Collectivity
  • 1998
  • In: Physical Review Letters. - 1079-7114. ; 80:12, s. 2558-2561
  • Journal article (peer-reviewed)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.

  • Strong population of a superdeformed band in Eu142
  • 1995
  • In: Physical Review C. - 0556-2813. ; 52:1, s. 99-103
  • Journal article (peer-reviewed)abstract
    • A superdeformed band has been found in Eu142. It is populated with 1.2(2)% of the total -ray intensity that decayed into Eu142 via the reaction Sn120(27Al,5n)142Eu at 152 MeV. The strength of the band is similar to that previously reported in Eu143, where the superdeformed band is populated with an intensity of 1.1(1)%. This is unexpected, since both total Routhian surface (TRS) and cranked modified oscillator (MO) calculations predict that the superdeformed band in Eu143 becomes yrast at lower spin than that in Eu142. This difference is 4Latin small letter h with stroke in the MO calculations and 8Latin small letter h with stroke in the TRS. Extrapolation of the normal-deformed yrast states in Eu143 shows, however, that a difference of 8Latin small letter h with stroke in spin corresponds to a change in the relative energy of the superdeformed and normal-deformed yrast lines of only 1 MeV.
