A=190区奇奇核超形变带顺排涌动量的相加性

Alignment Additivity of Superdeformed Bands of Odd-Odd Nuclei in A = 190 Region

利用推转玻尔-莫特森模型指定的能级自旋，研究了A＝190区奇奇核194Tl和196Bi超形变带的顺排角动量的相加性．194Tl的6条超形变带中，有4条满足顺排角动量的相加性规则，而196Bi的超形变带不满足这个规则．

Alignment additivity of the superdeformed (SD) bands in odd-odd nuclei 194 Tl and 196 Bi is investigared with the level spins determined by the Cranking Bohr-Mottelson Model. The alignments of four of the six SD bands in 194Tl can be accounted for from the additive contributions of SD bands of the neighboring odd-proton and odd-neutron nuclei, while that of the SD band 196Bi(1) can not.
