α decay of high-spin isomers in N=84 isotones

The superfluid tunneling model is applied to the calculation of half-lives of the observed \ensuremath{\alpha}decays in N=84isotones. Results of our calculations are compared to experimental data on the ground-state \ensuremath{\alpha}decays along the isotonic chain from ^{144}\mathrm{Nd}to ^{159}\mathrm{Re} Good agreement is found. The \ensuremath{\alpha}decays of the known high-spin isomers in $^{155}\mathrm{Lu},...
