摘要

We consider the systematics of α-decay half-lives of super-heavy nuclei versus the decay energy and the total α-kinetic energy.We calculate the half-lives using the experimental Qα values.The computed half-lives are compared with the experimental data and with existing empirical estimates and are found to be in good agreement.Also,we obtain α-preformation factors from the ratio between theoretical and experimental results for some superheavy nuclei and evaluate the standard deviation.The results indicate the acceptability of the approach.
