High spin states in 210Rn approaching the region of 3-particle-hole neutron excitations

The properties of high spin states in 210Rn have been investigated using the 198Pt(17O, 5n) reaction at a bombarding energy of 96 MeV. Decay properties for states up to an excitation energy of 12026+Δ keV and spin of (37−) have been deduced. The level scheme is compared with predictions of empirical shell model calculations. High lying states are interpreted in terms of multiparticle configurations which include single and double neutron core excitations. Configurations have been assigned for almost all of the observed levels. Agreement between experimental and calculated level energies is generally within 200 keV.
