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- and
-
coincidence measurements. A simple (
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
s.
