Role of quasiparticle structure in ? decay of superheavy nuclei

We use the superfluid tunneling model (STM) to calculate the half-lives of alpha decays of odd -A and odd -odd superheavy nuclei (SHN) with Z ?, 100 and A ?, 250. The experimental data are reproduced to accuracies comparable to other contemporary models of the alpha decay of the SHN. We then apply the STM to examine the influence of the quasiparticle structure on the properties of the chains of alpha decays arising from odd -A SHN. Using representative calculations of the one-quasi-particle structure of odd -Z and odd -N SHN, we illustrate the important role played by high -Q orbitals in defining the observed characteristics of the alpha-decay chains. We point out sources of possible ambiguity that may arise due to the quasiparticle structure when assigning alpha-decay chains to specific SHN.
