Abstract The β -delayed neutron-emission probabilities of 28 exotic neutron-rich isotopes Pm, Sm, Eu, and Gd were measured for the first time at RIKEN Nishina Center using Advanced Implantation Detector Array (AIDA) BRIKEN neutron detector array. existing -decay half-life ( T 1/2 ) database was significantly increased toward more isotopes, uncertainties previously values decreased. new data not only constrain theoretical predictions half-lives probabilities, but also allow probing mechanisms...
Production cross sections were measured for fragments produced by an 85 MeV/u Pt198 beam incident on a beryllium target. Event-by-event particle identification of A, Z, and q the reaction products was performed employing energy loss, time-of-flight, magnetic rigidity, total kinetic measurements. Over 70 nuclei in Hf-Pt region identified, including three isotopes first observed this work: Hf191,192 Lu189. Due to existence multiple charge states between H-like C-like ions, new analysis method...
The astrophysical origin for the chemical elements between first and second $r$-process peaks is a matter of intense debate, with number nucleosynthesis processes at explosive stellar environments possibly contributing to their production. Modeling neutron-capture that would produce these requires reliable data on trends neutron separation energies neutron-rich isotopes which are highly unstable not readily accessible by experiment. This work describes application an experimental technique,...
