α decay of the new isotope Pu 227

H. B. Yang, Z. G. Gan, Z.Y. Zhang, M. H. Huang et autres

The new isotope $^{227}\mathrm{Pu}$ has been produced in the fusion-evaporation reaction $^{192}\mathrm{Os}(^{40}\mathrm{Ar},5n)^{227}\mathrm{Pu}$ at the gas-filled recoil separator SHANS, and identified using a well-established implantation-decay correlation technique. From the nine observed decay chains, the $\ensuremath{\alpha}$-particle energy and half-life of $^{227}\mathrm{Pu}$ were measured to …

α decay of the new isotope 204Ac

Min Huang, Z.G. Gan, Zheng Zhang, Long Ma et autres

A new proton-unbound isotope 204Ac was produced in the fusion-evaporation reaction Tm(40169Ca,5n)204Ac and identified via the recoil-α correlation at the gas-filled recoiled separators SHANS2 and SHANS. The excitation function for producing 204Ac was measured and the optimal beam energy was evaluated to …

Theoretical study of evaporation cross sections in the synthesis of very neutron-deficient nuclei

Chengbin Wang, Z. Z. Ren

The synthesis of rare-earth neutron-deficient nuclei with large $Z/N$ ratio $\ensuremath{\approx}0.88$ is studied within the framework of the standard statistical model. The fusion cross sections are calculated on the basis of the nuclear reaction video model. The deexcitation process is calculated with …
