The internal pair conversion (IPC) of transitions in Pb nuclei has been studied. Recent calculations of IPC for transitions with energies up to 2 MeV predict large differences in the shapes of the angular correlations according to their magnetic or electric character. We have measured absolute pair-conversion coefficients for E1 transitions in {sup 206}Pb and an M1 transition in {sup 207}Pb with uncertainties three to five times smaller than previous measurements. The measured positron-electron angular correlations are in good agreement with the predictions of the recent calculations and display the predicted differences between the electric and magnetic cases. {copyright} {ital 1998} {ital The American Physical Society}
