Fully microscopic DWBA analyses on 89Y (α, p)92Zr reaction

The differential cross sections have been measured for the 89Y (α, p) 92Zr reaction with some low-lying states and the 89Y (α, α) 8(Y elastic scattering by using 26.1 MeV α beam. A fully microscopic DWBA analyses for 89Y (α, α) 92Zr have been performed by using 89Y and 92Zr shell-model wavefunction with or without the core excited configuration. With the core excited configuration, relative strengths of the ground state and the first excited state are greatly improved. Finally, the absolute cross sections for 89(α, p) 92Zr and importance of shallow well depth of α potential are discussed
