Inbeam \u03b3-ray excitation functions, \u03b3-\u03b3 coincidence measurements, and \u03b2+-delayed \u03b3-ray excitation functions have been used to identify thirteen levels in 106In. From this new level scheme the energy separation of the high-spin ground state and the low-spin isomer has been determined to be 28.6\u00b10.5 keV. The threshold energy of the strongest low-lying \u03b3-ray transition yields a mass excess for 106In of -80601\u00b115 keV. Spins for some states are suggested by comparing the excitation functions to Hauser-Feshbach calculations. In-beam \u03b3-ray excitation functions for the 108Cd(p,n\u03b3)108In reaction give a mass excess for the 3+ \u03b2+-decaying state in 108In of -84018\u00b112 keV.
