摘要：

We present a detailed analysis of the alpha-decay fine structure in 32 deformed odd-mass nuclei from Z = 93 to Z = 102. The alpha-decay half-lives are systematically calculated within the multichannel cluster model (MCCM), which turns out to well reproduce the experimental data and show the neutron deformed shell structure. The branching ratios for various daughter states are investigated in the MCCM and in the WKB barrier penetration approach, respectively. It is found that the MCCM results agree well with the experimental data, while the WKB results have relatively large deviations from the experimental data for the a transitions to the high-lying members of the rotational band.
