【摘要】 测量了⁸⁹Y（α,P） ⁹²Zr反应的基态和几个激发态的微分截面及⁸⁹Y（α,P） ⁸⁹Y弹性散射微分截面。利用⁸⁹Y、⁹²Zr核壳模型波函数对该反应基态和第一激发态的实验数据进行了完全微观DWBA理论分析。具体核芯激发组态的核波函数明显地改善了不同末态的截面相对强度,而对角分布的形状影响甚微。它表明具有核芯激发组态的⁸⁹Y、⁹²Zr核波函数有较好的实验基础。最后讨论了⁸⁹Y（α,P）⁹²Zr反应的截面绝对值问题,揭示了α光学势浅势阱的重要性。更多还原

【Abstract】 The differential cross sections have been measured for the 89Y (a, p) 92Zr reaction with some low-lying states and for the 89Y (a, a) 89Y elastic scattering by using 26.lMeV a beam. A fully microscopic DWBA analyses for 89Y (a, 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 89 (a, p) 92Zr and importance of shallow well depth of a potential are discussed.更多还原
