Abstract

Decay properties of the new neutron-deficient nuclide At192 have been studied in the complete fusion reaction Sm144(V51,3n)At192 at the velocity filter SHIP. Two isomeric states with half-lives of 88(6) ms and 11.5(6) ms, respectively, and with complex α-decay schemes were identified in At192. The decay pattern of one of the isomers suggests that it is based on the oblate-deformed π2f7/2 ν1i13/2 configuration, which confirms the expected onset of deformation in the At isotopes by approaching the neutron midshell at N=104. © 2006 The American Physical Society.
