利用△E-E望远镜及北京Q3D磁谱仪系统.在HI-13串列加速器提供的35MeVα离子轰击下,测量了~(56)Fe(аd)~(58)Co核反应的精细能谱和微分截面角分布.借助全微观DEBA理论分析,相应于核反应俘获的p-n核子对具有(lg_(9/2))~2组态,观测到迄今所能看到的最高拉长态(lg_(9/2),lg_(9/2))_9.还对6.4 MeV高激发能级核反应截面的反常增强,而p-n核子对耦合成最小角动量的实验证据进行了讨论,并且确认了6.4MeV能级为非自然宇称态,自旋字称值J~л=1~+.
Using the △ EE telescope and the Beijing Q3D magnetic spectrometer system, the fine energy spectra and the differential cross-section angles of the ~ (56) Fe (аd) ~ (58) Co nuclear reaction were measured under 35MeVα ion bombardment provided by the HI-13 tandem accelerator (Lg_ (9/2)) ~ 2, the maximum elongated state (lg_ (9/2)) observed so far has been observed. , lg_ (9/2)) _9. The anomalous enhancement of the nuclear reaction cross section at a 6.4 MeV high excitation level was also studied, and experimental evidence of the coupling of the pn nuclei to the minimum angular momentum was also discussed and it was confirmed that the 6.4 MeV level was unnatural The parity state, spin word value J ~ л = 1 ~ +.
