DECAY OF THE 9.4-MIN AND 8.7-DAY ISOMERS OF Sn$sup 12$$sup 5$
The decay schemes of the 9.4-min and 9.7-day isomers of Sn/sup 125/ were studied using scintillation spectrometers and coincidence techniques. Gamma rays of energies 325, 585, relative intensities 130, 0.75, 0.40, 0.16, 0.1None7, 1.0, 0.58, decay of the 9.4-min isomer while the decay of the 9.7-day isomer gives rise to gamma rays of energies 330, 470, 810, tensities 0.23, 0.28, 1.0, 0.92, 2.81, 0.09, 0.09, 0.41, and 0.03, respectively. On the basis of the coincidences between the various gamma rays it is concluded that the 9.4-min isomer excites levels in Sb/sup 125/ at 325, 640, 910, 1470, 1720, and 1940 kev, whereas levels at 1075, 1410, 1885, 1985, and 2230 kev are excited in the decay of the 9.7-day isomer. Further evidence in support of these levels from totalabsorption gamma spectra is also presented. Plausible spin and parity assignments to these levels have been made on the basis of the log ft values of the beta groups feeding these levels and also their decay modes. (auth)
