✦ Synopsis

Two-photon laser-induced fluorescence and "2+ 1" multiphoton ionization detection of silicon (3PJ., 'DJ atoms was accomplished using the 4 'PJ + 3 'P,,.., 4 'S, t3 'Pr, and the 4 ID,+3 'Dz resonant two-photon transitions. Silicon atoms were produced in their ground 'Pp (J" =0,1,2) and first singlet 'D* states by the multiphoton dissociation of Si(CH3), in the wavelength region 400-460 nm. Line strength intensities for the two-photon transitions originating from the 3 'P,. (J" =O, 1,2) states were calculated and compared to experimental values determining that the silicon ('P,.) atoms were produced in a statistical population distribution.
