Abstract
The (n,n'gamma) reaction has been used to study the properties of low-lying excited states of Pb-207. Gamma-ray excitation functions, angular distributions, and coincidences have been measured, and the lifetimes of many excited levels were determined with the Doppler-shift attenuation method (DSAM). A sextuplet of states near 3.2 MeV is interpreted as resulting from particle-vibration coupling of the f(5/2) neutron hole, the first excited state of Pb-207, with the octupole phonon of the Pb-208 core.
