摘要:

在达姆施塔特的GSI的R3 B-LAND装置上,使用库仑激发在束能量约为500 MeV/u的逆运动学中测量了外来Ni同位素。由于实验装置允许运动学完整的测量,激发能重建使用不变质量的方法。在68 Ni中观察到GDR和附加的低强度,后者消耗了E1能量加权和规则的4.1(1.9)%。此外,测量了激发态~(68)Ni核的非统计衰变的分支比,其值为24(4)%。

英文摘要:

Exotic Ni isotopes have been measured at the R3B-LAND setup at GSI in Darmstadt, using Coulomb excitation in inverse kinematics at beam energies around 500 MeV/u. As the experimental setup allows kinematically complete measurements, the excitation energy was reconstructed using the invariant mass method. The GDR and additional low-lying strength have been observed in 68Ni, the latter exhausting 4.1(1.9)% of the E1 energy-weighted sum rule. Also, the branching ratio for the non-statistical decay of the excited 68Ni nuclei was measured and amounts to 24(4)%.
