Abstract：
The differential cross sections have been measured for the ⁸⁹Y(α,p) ⁹²Zr reaction with some low-lying states and for the ⁸⁹Y(α,α)⁸⁹Y elastic scattering by using 26.1MeV α beam.A fully microscopic DWBA analysis for ⁸⁹Y(α,p) 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 ⁸⁹Y(α,p) ⁹²Zr and importance of shallow well depth of α potential are discussed.
