英文摘要	High-spin states of Rn-207 have been investigated via the Pt-196((16)0,5n)Rn-207 reaction at O-16 energies from 85 to 95 MeV using techniques of in-beam gamma-ray spectroscopy. The measurements of gamma-ray excitation fuction, gamma-ray spectra, gamma-gamma-t coincidences and decay gamma-ray spectra were performed with 10 BGO (AC) HPGe detectors. Based on these measurements, a level scheme of Rn-207 with 17 gamma rays is established. The spins for most of the levels in the scheme are proposed according to the results of measured gamma-ray DCO ratios. Comparing the structure between Rn-208 and Rn-207, the low-lying levels in Rn-207 are interpreted by coupling a valence neutron hole (f(5/2)) to the excited states in Rn-208 core.
