Abstract ： Excited states in 207 Rn are investigated via the 196 Pt(16 O,Sn)207 Rn reaction at beam energies from 85 to 95 MeV using techniques of in-beam γ-ray spectroscopy. Measurements of γ-ray excitation function, x-γ and γ-γ-t coincidences are performed with ten BGO(AC)HPGe detectors. Based on these measurements, a level scheme of 207 Rn, including 17 γ-rays and 18 levles, is established. Spins for most of the levels are proposed according to the measured DCO ratios. The level structure is compared with a weak-coupling calculation using the interaction energies extracted from neighbouring nuclei.
