Photoelectrons that leave the residual Pb ion in the 6s/sup 2/6p( /sup 2/P/sub 1/2/) and 6s/sup 2/6p( /sup 2/P/sub 3/2/) states were observed from the ionization threshold (7.42 eV) to 12 eV. Partial and total cross sections were obtained, the latter also from ion measurements. The 6p/sub 1/2/ cross section was found to be unexpectedly small near threshold (/sup 2/P/sub 1/2/), but strongly enhanced near the /sup 2/P/sub 3/2/ threshold associated with the admixed 6p/sub 3/2/ configuration. The 6p/sub 3/2/ cross section is unusually large at threshold.
