The experiments described in the report are directed to eventually estimate an f number that describes the photoionization out of the singlet D and triplet D metastables of barium. The parameter actually measured is the relative total loss of atoms from each of the four paramagnetic metastables in barium the loss in metastable density is monitored by bombarding an atomic beam of excited barium with a narrow band of light. This total f number, over the light bandpass region being investigated, must be reduced by taking into account all bound-bound transitions that depopulate these particular metastables. These laboratory experiments were performed using the Cornell Aeronautical Laboratorys molecular beam magnetic resonance apparatus CAL MBMRA to separate out and measure metastable densities. A description of this instrumentation is included in the report. Author
