利用 240-MeV {alpha} 粒子在小角度（包括 0 度）的非弹性散射，研究了 {sup 48}Ca 中 9.5 MeV < E{sub x} < 40 MeV 的巨型共振区域。 E0 能量加权总和规则 (EWSR) 的 95{sub -15}{sup +11}%、E2 EWSR 的 83{sub -16}{sup +10}% 和 E1 EWSR 的 137 {+-} 20% 位于 E{sub x}=40 MeV 以下。还给出了实验数据与在基于平均场的随机相位近似中获得的等标量巨单极子共振的计算结果的比较。
The giant resonance region from 9.5 MeV < E{sub x} < 40 MeV in {sup 48}Ca has been studied with inelastic scattering of 240-MeV {alpha} particles at small angles, including 0 deg. 95{sub -15}{sup +11}% of E0 energy-weighted sum rule (EWSR), 83{sub -16}{sup +10}% of E2 EWSR, and 137 {+-} 20% of E1 EWSR were located below E{sub x}=40 MeV. A comparison of the experimental data with calculated results for the isoscalar giant monopole resonance, obtained within the mean-field-based random-phase approximation, is also given.
