DOIAbstract
International audience2+ and 1− states in Zr90 were populated via the (O17,O′17γ) reaction at 340 MeV. The γ decay was measured with high resolution using the AGATA (advanced γ tracking array demonstrator array). Differential cross sections were obtained at few different angles for the scattered particle. The results of the elastic scattering and inelastic excitation of 2+,3−, and 1− states are compared with distorted-wave Born approximation (DWBA) calculations, using both the standard collective form factor and a form factor obtained by folding microscopically calculated transition densities. This allowed to extract the isoscalar component of the 1− state at 6.424 MeV. The comparison of the present (O17,O′17γ) data with existing (γ,γ′) and...
