摘要
通过 OO 反应在 8 MeV 的条件下进行 O 的激发态 射线光谱学研究。利用动力西移衰减法（Doppler Shift Attenuation Method），确定了 2 和 3 态的寿命。从 O 2 和 3 态的 射线分支和 E2/M1 混合比中，确定了 B(E2) 和 B(M1)。比较了各种手术有效场论哈密顿量（描述超出基态的核性质）以及标准 USDB 相互作用与实验获得的数据。首次在远离稳定性核中对大量 射线跃迁概率与中等相似性重整化群初步计算中所涉及的价值空间进行比较。结果表明，手术有效场力在详细的高精度光谱学性质方面受到了挑战。发现简化跃迁概率是检验初步模型性能的非常严格的测试。
