Electron affinities of halogen atoms
Abstract On the basis of an appropriate form of interaction potential, which has been proposed recently as a modification of the Gaussian potential, an expression for the electron affinity has been obtained. The values of the electron affinity for the four halogen atoms were calculated from the expression utilizing the molecular constants ( r e , k e , D e and I ) data for twenty alkali halide molecules and were compared with most reliable experimental values of Berry and Reimann. The agreement is satisfactory.
