Abstract
The authors have calculated two-photon electron detachment cross sections of the 5p shell of negative iodine in the photon energy region 0-1 Ryd. The results cover the region from the two-photon ionisation threshold of I- at 0.12 Ryd to well above the one-photon ionisation threshold of neutral iodine at about 0.8 Ryd. They demonstrate the importance of many-electron screening effects and double excitations in different regions of photon energies.Keywords
