Metastable States of ${\mathrm{Re}}^{180}$, ${\mathrm{Ir}}^{191}$, ${\mathrm{Au}}^{193}$, ${\mathrm{Pb}}^{201}$, and ${\mathrm{Pb}}^{203}$

Ten elements of atomic number between 60 and 82 have been bombarded with 31.5-Mev protons and examined for activities with half-lives between 0.5 and 200 seconds. None were observed in Sm, Ho, Tm, Lu, and Ta. Those produced in W, Ir, Pt, Au, and Tl were investigated with scintillation and proportional counters. Isotope assignments were made on the basis of excitation function studies. Observed were ${\mathrm{Re}}^{180m}$ (145 seconds), ${\mathrm{Ir}}^{141m}$ (4.9 seconds), ${\mathrm{Au}}^{193m}$ (3.9 seconds), ${\mathrm{Au}}^{195m}$ (31 seconds), ${\mathrm{Au}}^{197m}$ (7.4 seconds), ${\mathrm{Pb}}^{201m}$ (60 seconds), and ${\mathrm{Pb}}^{203m}$ (6.7 seconds). Decay schemes are proposed and some regularities are discussed.
