英文摘要	Besides alpha-decay energies and half-lives, more information on nuclear structure properties can be obtained from fine structure observed in a decay. The multi-channel cluster model (MCCM) for well-deformed alpha emitters has very recently been proposed for a precise description of the alpha-decay fine structure. In this paper, based on the neWly proposed Q alpha formula and the predicted rotational energy for superheavy nuclei, we present a theoretical prediction of the fine structure in the alpha decay of deformed Rf, Sg, and Hs isotopes within the MCCM. The branching ratios to various daughter states and total alpha-decay half-lives are evaluated by the five-channels microscopic calculations. Any adjustable parameter is not introduced in our calculations. This is, to our knowledge, the first coupled-channel study of the alpha-decay fine structure in superheavy nuclei. It is expected that the present predictions would be useful for ongoing or future experiments on structure researches of superhezwy nuclei.
