Abstract
A reanalysis of old data removes the (,) ambiguity for a very narrow state at MeV and gives a unique assignment. Such a state corresponds well to a predicted state at 11.494 MeV of unusually small reduced widths for decay to both the ground and first excited state of . This new state is a better band head for the 8p-4h states at 15.159 MeV () and 18.538 MeV () than the currently accepted state at 12.44 MeV. Possible and members are considered. The higher level at starts a new band, and candidates for this band are critically discussed.
