Abstract
The very neutron-deficient isotope Sm-133 was produced by irradiation of an enriched target of Ru-96 with Ca-40 and studied by using a helium-jet fast tape transport system in combination with X-gamma and gamma-gamma coincide nce measurements. A simple (EC + beta (+)) decay scheme of Sm-133 was propo sed for the fi-ist time. As a by-product Pr-133 was produced simultaneously because of the Ru98-102 content of the ruthenium target. The half-life of a 11/2(-) low-lying isomeric state in Pr-133 was measured to be 1.1 +/- 0.2 s.
