High-spin isomer inRn211, and the shape of the yrast line

Abstract
High-spin yrast states in Rn211 have been identified. A 612, 380 ns isomer found at 8856 keV is characterized as a core-excited configuration. The average shape of the yrast line is smoother than that of its neighbor Rn212. This difference is attributed to the presence of the neutron hole.
