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