Dependence of the populations of low-energy levels in Ag-108,Ag-110 on theresonance spin and parity - art. no. 054616

Measurements of prompt gamma rays, following neutron capture in Ag-107 and Ag-109 have been performed at the GELINA facility in the resonance energy r egion up to about 1 keV. From the intensities of low- and high energy gamma rays the spins of 53 Ag-107 and 78 Ag-109 s- and p-wave resonances have be en assigned. These spectroscopic quantities are important for the interpret ation of data from parity violation experiments performed by the TRIPLE Col laboration. The intensities of low-energy transitions showed a dependence n ot only on the spin of the resonance but also on its parity. This effect al lows the assignment of the parity of the resonances and may open new perspe ctives in the study of the gamma decay of the compound nucleus.
