Decay of neutron-deficientIn103andCd103isotopes

The decays of neutron-deficient ${}_{}{}^{103}{}_{}{}^{}\mathrm{In}$ and ${}_{}{}^{103}{}_{}{}^{}\mathrm{Cd}$ have been investigated. Sources were produced by (${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$, $yp-xn$) reactions on a natural Mo target. Singles spectra and various coincidence spectra involving $\gamma$ rays, x rays, positrons, and conversion electrons have been performed on mass separated samples. The newly discovered activity ${}_{}{}^{103}{}_{}{}^{}\mathrm{In}$ ($T_{\frac{1}{2}}=1.08\mathrm{}\pm 0.11$ min) was found to populate mainly the $\frac{7}{2^{+}}$ excited ${}_{}{}^{103}{}_{}{}^{}\mathrm{Cd}$ state at 188 keV. About 200 lines were attributed to the 7.3 min ${}_{}{}^{103}{}_{}{}^{}\mathrm{Cd}$ decay. Coincidence relationships are given. A level scheme of ${}_{}{}^{103}{}_{}{}^{}\mathrm{Ag}$ is proposed.
