AN APPROACH TO MULTIPHOTON IONIZATION AND AUTOIONIZATION OF SI-I

We have studied multiphoton ionization and autoionization in atomic si licon using a configuration interaction Hartree-Fock-Dirac method (CIH FD). We have obtained new results for part of the autoionization spect rum as well as photoionization cross sections at a laser frequency of 0.121 au into three open continua. This information provides a startin g point for further theoretical development as well as a basis for som e initial experimental comparison in such complex atomic systems with presently available lasers.
