extensive new date on the even parity j=o and j=2 levels of neutral barium have been obtained using two-photon absorption spectroscopy with a nitrogen-pumped dye laser and space-charge detection. members of the rydberg series 6sns/sup 1/s/sub 0/(16 n 61), 6snd/sup 1/d/sub 2/ (15 n 81), and 6snd/sup 3/d/sub 2/ (15 n 30) and perturbing levels of these series belonging to the 5d7d configuration have been observed: the corresponding wave numbers have been determined. a detailed description of the experimental method is given, followed by the presentation of the new data and the theoretical analysis of the j=0 spectrum. all j=0 levels in the energy range between 34370 cm/sup -1/ and the first limit were interpreted by means of the multichannel quantum-defect theory. in this energy range, the 6sns/sup 1/s/sub 0/ series is perturbed by two levels at 38924 and 41441 cm/sup -1/: these levels are assigned to 5d6d/sup 1/s/sub 0/ and 5d7d/sup 3/p/sub 0/, respectively
