Abstract.

Cluster states up to 12 MeV in the stable light nucleus 21Ne, based on the 16 O + n + α molecular configurations, have been populated in the incomplete-fusion reaction 16  8 O(7 3 Li, np)21 10 Ne at 29.4 MeV. The observation of both intra- and inter-band transitions leads to a re-interpretation of some levels in the K π = \( {\frac{{3}}{{2}}}\) - and K π = \( {\frac{{1}}{{2}}}\) - bands. The implications of this re-ordering on the octupole doublet bands are examined. The data allow a more accurate determination of some previously uncertain level energies. The “missing” I π = \( {\frac{{5}}{{2}}}\) - level is also discussed.
