| 英文摘要 | A comprehensive investigation of the superdeformed bands observed in (EU)-E-142,143,144,147 was given. The fluctuation in the transition energies has been removed. The smoothed transition energies were fitted by the ab-expression or its modification. The spins of these bands, except for band 4 of (EU)-E-147, have been assigned conclusively. The exit spin in (EU)-E-143 was Proposed to be 29/2, different from that asserted to be determined experimentally but remains to be confirmed. The corresponding values in (EU)-E-142 and Eu-144(a) are 21 and 28, lower than those proposed in the literature by 6 and 8 units, respectively. Two pairs of superdeformed bands in (EU)-E-147, i.e. bands 1,5 and bands 2,3 were proposed to be signature partners. The exit spins are 53/2 and 63/2 for the former pair, and 43/2 and 41/2 for the latter pair. In addition, both of them have a rather large de-coupling constant(approximate to -l), implying they are of K=1/2 and built on the single particle level v[651] down arrow or pi [530] down arrow. This assignment may be helpful for the studies of the so-called identical bands and pseudospin problem. The signature partner pairs observed in (EU)-E-144,148 are not included in the investigation. |
