Abstract

High-spin states in ²²Ne have been studied using the ¹⁴C(¹²C,α)²²Ne(α)¹⁸O reaction at E(¹² C)= 44MeV. The spin assignments were obtained as results of the analysis of double (α, α) angular correlations with the residual ¹⁸O nucleus in the 0⁺ ground state. The obtained values of spin and parity of five levels are: 20.0 MeV (9⁻), 20.7 MeV (11⁻), 21.6 MeV (9⁻), 22.2 MeV (12⁺), 25.0 MeV (9⁻).
