Abstract
Properties of excited states in 108 Ag and 110 Ag were studied using the 108 Pd(p, nγ) 108 Ag and 110 Pd(p, nγ) 110 Ag reactions. The low-lying level schemes of 108 Ag and 110 Ag were built from the γ-ray excitation functions. Spins were assigned by comparing the measured γ-ray angular distributions and excitation functions with predictions of the statistical compound-nucleus model. The following spin-parity assignments were obtained for the levels and nuclei indicated: 192.7 keV, 1 + or (2 + ); 206.2 keV, 2 + ; 215.1 keV, 3 + ; 294.5 keV, 2 (+) ; 324.4 keV, 3 + ; 338.4 keV, 3 - and 379.4 keV, 1 - for 108 Ag and 118.7 keV, 3 + ; 191.2 keV, 3; 198.3 keV, 2 and 267.0 keV, (0, 1, 2) for 110 Ag. With the methods of pulsed-beam delayed coincidence and pulsed-beam DPAD, lifetimes and g -factors of isomeric states in both nuclei were measured. The results are T 1/2 =45.8±0.7 ns and g =+1.301±0.011 for the 215.1-keV state of 108 Ag and T 1/2 =36.7±0.7 ns and g =+1.242±0.012 for the 118.7-keV state of 110 Ag.
