通过重核区中壳层强度变化的系统性实验研究，可以使人们更好地了解超重核的壳层结构。在此基金支持下，本项目将利用数字化数据获取系统结合充气谱仪研究新核素224Np的合成及其衰变性质，即从Z～92，N～126核区的丰中子端开始研究这一核区的壳层强度变化系统性。若条件允许，本项目还将尝试进一步合成新的核素227Pu。

Obtaining information about the evolution of nuclear shell closures in the heavy-element region is a prerequisite for gaining an improved understanding of superheavy nuclei. We propose to synthesize and study the decay properties of the new neutron-rich isotope 224Np with the digital data acquisition system and the gas-filled separator, as the first step for studying the evolution of N=126 shell closure in the region Z～92. If there are sufficient conditions, this project will try to synthesize the new isotope 227Pu further.
