Directional-correlation measurements have been made on the 1770-570 keV, 1442-897 keV, and 1063-570 keV, ..gamma..-ray cascades of /sup 207/Pb, using an automated rotating-detector Ge(Li) -NaI(Tl) coincidence spectrometer. The present results imply an E5/M4 multipole mixing ratio delta (1063) = 0.016(11) and E2/M1 mixing ratios delta (1770) = +0.082(15) and delta (897) = +0.075(25). The values obtained by averaging these and previous results are delta (1770) = +0.087(5), delta (1063) = +0.020(10), and delta (897) = +0.089(11). When these values are compared to the single-neutron-hole calculations made in the oscillator basis with h..omega..=7.6 meV, the best over-all agreement is obtained for the neutron-hole effective charge epsilon/subn/approx. =0.89.
