Abstract

Detailed alpha-decay studies of the neutron-deficient isotope At-194 have been performed in the complete fusion reaction Fe-56+Pr-141 -> At-194+3n at the velocity filter SHIP. Two alpha-decaying isomeric states with half-lives of T-1/2(At-194(m1))=310(8) ms and T-1/2(At-194(m2))=253(10) ms were identified in this nucleus. Their complex decays to the states in the daughter nucleus Bi-190 are discussed in the article. We propose that similar to the case of the neighboring At-191,At-192,At-193,At-195 isotopes, the oblate-deformed configurations based on the proton 1/2(+)[440] and/or 7/2(-)[514] Nilsson orbitals become important in At-194. A new isomeric state with the half-life of 175(8) ns was observed in Bi-190.
