[en] 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(1g_9/2^-1)·ν(1h_11/2 2d_3/2)7^-] 19/2^- has been assigned to it on the basis of the measured g-factor, g_exp=+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)
