合成了新的同位素，并在KISS装置的多核子转移反应中系统地测量了19个丰中子帕-钚同位素的原子质量。目前的实验结果表明，多核子转移反应对获取未被探测的富含中子元素的榄系元素同位素在这一核素区域的剪切带隙中起着至关重要的作用。
The new isotopewas synthesized and systematic atomic mass measurements of nineteen neutron-rich Pa-Pu isotopes were performed in the multinucleon transfer reactions of thesystem at the KISS facility. The present experimental results demonstrate the crucial role of the multinucleon transfer reactions for accessing unexplored neutron-rich actinide isotopes toward theshell gap in this region of nuclides.
