摘要: Abstract Low background α spectroscopy of 223Ra and daughter products shows 14 new levels in 219Rn, 7 215Po, 2 211Pb one 207Tl. This second excited state Tl is not h 11 . The 219Rn 215Po are difficult to fit reasonably with the collective model as long information on spins absent for all low intensity.
