Excitation of ground and gamma bands in the ^2^4Mg(α, α')^2^4Mg reaction at 120 MeV

The cross sections for excitation of the members of the ground state (g.s.) band 0^-(g.s.), 2^+ (1.37 MeV) and 4^+ (4.12 MeV) and the γ-band 2^+"γ (4.24 MeV), 3"γ^+(5.24 MeV) and 4"γ^+(6.01 MeV) in ^2^4Mg have been measured in inelastic α-scattering at E"α = 120 MeV. The excitati...

The cross sections for excitation of the members of the ground state (g.s.) band 0^-(g.s.), 2^+ (1.37 MeV) and 4^+ (4.12 MeV) and the γ-band 2^+"γ (4.24 MeV), 3"γ^+(5.24 MeV) and 4"γ^+(6.01 MeV) in ^2^4Mg have been measured in inelastic α-scattering at E"α = 120 MeV. The excitation of these states are found to be well described by a coupled-channel calculation (CCBA) performed in the framework of the asymmetric rotational model. Two sets of parameters are found to give excellent fits to the data, but in both a direct coupling between the ground state and the 4^+ state is found necessary. Ausführliche Beschreibung
