Abstract
Excited states in 217 Ra were studied for the first time by the in-beam spectro-scopic techniques. Reactions used were 208 Pb( 12 C, 3n) 217 Ra and 108 Pb( 13 C, 4n) 217 Ra at 70 and 80 MeV, respectively. The γ-rays in 217 Ra were identified based on the γ-ray excitation functions and the αγ-coincidence experiment. The level structure established in this study consists of three streched E2 cascades. Those states are interpreted to arise from the coupling of a valence neutron to the quadrupole- and octupole-phonon. An isomeric state with a half-life of 4.1±0.3 ns was found at 2388 keV with a spin-parity (31/2 - ).
