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