Excited levels of 186Re have been studied using results of the single γ-ray spectra measurements following the thermal neutron capture reaction. Energies and intensities of more than 500 γ-transitions have been obtained with the high-resolution crystal diffraction spectrometer GAMS5 of ILL. Most of the obtained intense γ-transitions have been placed in the 186Re level scheme. A number of new levels, as well as the depopulation for levels observed earlier in the 187ReRe reaction measurements have been proposed. Structure of 186Re levels is interpreted in terms of two-quasiparticle plus rotor coupling model and compared with that of the neighbouring doubly-odd nucleus 188Re.

186 Re核的新旋转水平
使用热中子捕获反应后的单个γ射线光谱测量结果研究了186 Re的激发水平。用ILL的高分辨率晶体衍射光谱仪GAMS5获得了超过500个γ跃迁的能量和强度。大部分获得的强γ跃迁已放置在186 Re能级方案中。许多新的水平,以及早在187 Re已经提出了反应测量。186 Re能级的结构根据两准粒子加转子耦合模型进行解释,并与相邻的双奇数核188 Re进行比较。
