d-3 H阈值下中子-~ 4 He共振散射

Neutron-4He Resonant Scattering at d-3H Threshold

Bernard Hoop, Gerald M. Hale, Petr Navratil

摘要:

速度图和时间延迟分析证实了5 He中最低3/2+能级的两极S矩阵结构。中子-α弹性和~ 4 He(n,d)~ 3 H反应极能量的实部分别为17.669+/-0.006和17.705+/-0.001MeV n-4 He c.m.,分别中子-α弹性共振,未修正的实验能量扩散,其特征在于氘和中子的部分宽度约。0.008和0.030兆电子伏建议由以前的时间延迟分析。

英文摘要:

Speed plot and time delay analysis confirms a two-pole S-matrix structure of the lowest 3/2+ level in 5He. Real parts of neutron-alpha elastic and 4He(n,d)3H reaction pole energies are 17.669+/-0.006 and 17.705+/-0.001 MeV n-4He c.m., respectively. Neutron-alpha elastic resonance, uncorrected for experimental energy spread, is characterized by deuteron and neutron partial widths ca. 0.008 and 0.030 MeV suggested by previous time delay analysis.
