-V spectrum of silicon and related energy level diagram

Abstract

The satellite spectrum of silicon is reported. It is found to consist of three lines at 1891.4, 1896.7 and 1903.0 eV. These have been assigned to the - group of transitions. The transition array has been, for the first time, analysed in terms of ten components as against the four reported in the literature. The relative contribution of each of the ten components in emitting these lines has been estimated and hence these lines have been identified as , and satellites, respectively. A weak structure at 1885.0 eV, in addition to the - spectrum, has also been observed and has been tentatively assigned to a - hypersatellite transition. The energy level diagram for the , and levels has also been presented.
