Query: Alpha-decay lifetimes semiempirical relationship including shell effects   A new version of the semiempirical formula based on fission approach of alpha
decay is derived, by using the optimum values of the fitting parameters
determined for even-even nuclei, combined with hindrance factors for even-odd,
odd-even, and odd-odd nuclides. The deviations from experimental data for two
regions of nuclear chart (493 alpha emitters with Z=52-118 and 142 transuranium
nuclei including superheavies (Z=92-118), respectively) are compared with those
obtained by using the universal curve and the Viola-Seaborg semiempirical
relationship.
