A resonant ionization spectroscopy apparatus was designed, built, and used to perform spectroscopy on the 2s2 1S0 - 2s2p 1P1 transition in neutral beryllium-9. Preliminary data indicates that a sub-Doppler resonant ionization spectrum can be obtained through an optical setup similar to that used in saturated absorption spectroscopy. The apparatus was unable to detect the triplet state 2s2p 3P0,1,2 - 2s4s 3S1 beryllium transition; possible experimental improvements are suggested to allow future spectroscopy of this state. Results from precision saturated absorption spectroscopy on the 2s2 1S0 - 2s2p 1P1 state are also presented.
