Abstract

We investigate optical properties of semiconductor atoms by absorption and emission spectroscopies. Each of ³P_J' - ³P°_J transitions except for J'=0 (the total angular momentum of the ground state) is confirmed in broad emission spectra in a hollow-cathode discharge in which negative electrodes incorporate semiconductor atoms that are evaporated in the discharge. For finer spectroscopies, the ³P₁ - ³P°₀ cyclic transition for laser cooling of silicon atoms at 252 nm is investigated in absorption spectra with a single-frequency tunable deep-UV coherent light source, which has a high potential for controlling their nuclear spins.
