Abstract
A spectroscopic investigation of the radon isotopes was performed by means of the reactions (,) and (,) with energies between 85 and 110 MeV and energies between 80 and 94 MeV. coincidences, pulsed beam yield functions, angular distributions, and pulsed beam isomeric decay rates were measured. The yrast and near-yrast level structure was established to , and in each of the three nuclei two isomers above the known state were observed. The systematic trends for the isotopes are compared with the behavior expected in a single particle model, and increased collectivity is found with decreasing neutron number. Analogies are made with the system.
