Abstract
Magnetic-rotational bands in the nearly spherical nuclei 197Pb and
199Pb and their decay to the normal states have been investigated by in-beam
conversion electron spectroscopy following (heavy ion,xn)
reactions. The expected M1 multipolarity of the in-band transitions
has been confirmed for the strongest bands and the multipolarity
of several transitions in the decay of the bands has been determined.
