Abstract
Excited states in 207Rn are investigated via the196Pt(16O,Sn)207Rn reaction at beam energies from85 to 95 MeV using techniques of in-beam γ-ray spectroscopy.Measurements of γ-ray excitation function, x-γ and γ-γ-tcoincidences are performed with ten BGO(AC)HPGe detectors. Based onthese measurements, a level scheme of 207Rn, including 17 γ-raysand 18 levels, is established. Spins for most of the levels areproposed according to the measured DCO ratios. The level structure iscompared with a weak-coupling calculation using the interactionenergies extracted from neighbouring nuclei.
