Abstract
The emission spectrum of indium has been photographed over the spectral range from 340 to 6500 AA using a disruptive electrodeless discharge and a spark in helium as sources. The analysis of In III has been revised and extended and now includes 4d10ns (n=5 to 12), 4d10np (n=5 to 9), 4d10nd (n=5 to 9) and 4d10nf (n=4 to 7). Polarisation theory has been applied to the 4d10ng (n=5 to 9) and 4d10nh (n=6 to 9) series and the ionisation potential deduced to be 226191 cm-1. The dipole polarisability of the 4d10 core is estimated to be 3.45 a03. Most of the expected terms of 4d95s5p are established for the first time.Keywords
