Prediction of {alpha}-decay half-lives and Q{sub {alpha}} values of superheavy nuclei by a global potential for {alpha} + nucleus systems

An approach we have proposed recently for calculation of Q{sub {alpha}} energy and decay half-life T{sub 1/2}{sup {alpha}} on the {alpha} decay of radioactive heavy ions is applied to the evaluation of these two important parameters for the nuclei in the superheavy region Z = 112-118 for which experimental data are not available. It is shown that the {alpha} + nucleus potential represented by an exactly solvable potential used in the calculation could be expressed in terms of proton (Z) and neutron (N) numbers of the {alpha} emitter so that varieties of {alpha}-emitting nuclei differing in their Z and N values could be addressed for their decay properties without the help of any adjustable parameter and the results of Q{sub {alpha}} and T{sub 1/2}{sup {alpha}} for a nucleus are estimated without any prior knowledge of any one of these quantities. This procedure to obtain the values of Q{sub {alpha}} and T{sub 1/2}{sup {alpha}} works well to reproduce the known experimental results for superheavy nuclei and hence, the procedure is expected to provide proper information about these parameters in experiments on {alpha} decay of new nuclei in the superheavy region.
