In-beam study of174Lu isomers

Levels in174Lu have been investigated using the176Yb(p,3n) reaction. Prompt and delayedγ-ray spectra have been observed with a 0.56-cm3 Ge(Li) detector by a multispectrum analysis method. The half-life and decay mode of two isomeric levels, one at 240.8keV (395±15ns) and the other at 365.1keV (145±3ns) have been firmly established. Hindrance factors are discussed. New delayed transitions in175Lu are also noted.

In-beam gamma-ray studies with tritons

Abstract The (t, 2n) reaction has been used to study gamma rays from targets of 208Pb and 204Hg as a method of investigating this in-beam reaction. Although the methods and results are similar to those obtained from the (α, 2n) and (p, 2n) reactions, the (t, 2n) reaction is capable of populating with large cross sections nuclei which cannot be stronglu populated by other reactions. Both the excitation function and gamma-ray angular distribution data yield useful information for spin assignments.
