摘　　要：对于近年来清华大学与美国合作研究组在原子核结构实验研究中有关奇A核的多声子γ振动带方面的进展进行了评述。研究人员通过有效的国际合作,识别了质量数A=100丰中子核区的奇A核103Nb,105Mo,107Tc和109Tc中的两声子γ振动带,这是迄今为止国际上在奇A核的结构研究中发现的仅有的4例这样的结构。对于实验方法、研究结果以及这些多声子γ振动带的特性进行了评述,并对目前在多声子带其他方面的研究及今后进一步的工作进行了概述。The experimental research on multi-phonon T-vibrational bands in odd-A nuclei by our international col- laboration has been reviewed. The two phonon T-vibrational bands in ^103Nb, ^105Mo, ^107Tc and ^109Tc in the A = 100 neutron-rich nuclear region were identified, which are the only four such bands discovered in nuclear structure studies until now. The experimental methods and results are summarized, and the characteristics for these band structures are discussed. The other aspects for our research on the multi-phonon vibrational bands as well as our future research work are also briefly reviewed.
