Abstract

He I_alpha photoelectron spectra have been measured for the I^- 5p⁶ shell of all diatomic alkali iodides for emission at 90 degrees and 26 degrees to an unpolarised photon beam. ²P _3/2:²P_1/2 branching ratios are reported for these angles. By assuming an asymmetry parameter for ionisation to the ²P_3/2 state of I values are calculated for ionisation to the ²P_1/2 state and absolute branching ratios are found. Results calculated in this way are discussed in terms of existing measurements for the equivalent states of xenon and of the ionic/covalent character of the iodide.
