High-spin states in 22Ne
Abstract
The structure of high-lying states in 22Ne has been studied using the 14C(12C,α)22Ne reaction at E(12C)= 44 MeV. The spins were determined by measuring double (α,α) angular correlations. Selective population of the 9- and 11- states at Ex=20.1 and 20.7 MeV, respectively, identifies those states as the 9- and 11- members of the first Kπ = 0- band, whose lower members were investigated by a method using inverse kinematics and a thick gas target. The spin and parity of four other new levels were determined to be 9- (21.5 MeV),12+ (22.1 MeV),9- (25.0 MeV) and 8+ (22.9 MeV). The two levels 9- and 12+ may belong to the rotational doublets.
