Pulsed beam experiments on 119Sb and 112In nuclei

The properties of short-lived isomeric states in 119Sb and 112In, populated in the reactions 118Sn(d,n), 119Sn(d,2n), 112Cd(d,2n) and 109Ag(α,n), have been investigated by pulsed beam γ-ray spectroscopy and TDPAD method. A new 19/2 - 136 ns isomeric state has been identified at 2553.3 keV in 119Sb and the intruder configuration [π(1g9/2-1)·ν(1h11/2 2d3/2)7-] 19/2- has been assigned to it on the basis of the measured g-factor, gexp=+0.331(6). Experimental information concerning the decay scheme of the short-lived isomeric states in 112In has been obtained. A new 6.32 keV M1 transition has been observed in this decay scheme and a mixed E1+5%M2 multipolarity has been assigned to the known 263 keV isomeric transition.(authors)
