摘要

The very neutron-deficient isotope ~(133)Sm we produced by irradiation of an enriched target of ~(96)Ru with ~(40)Ca and studied by using a helium-jet fast tape transport system in combination with X-γ and γ-γ coincidence measurements. A simple (EC + β~+) decay scheme of ~(133)Sm was proposed for the first time. As a by-product ~(133)Pr was produced simultaneously because of the ~(98-102)Ru content of the ruthenium target. The half-life of a 11/2~- low-lying isomeric state in ~(133)Pr was measured to be 1.1 ± 0.2 s.
