论文摘要
在本文中，提出了一种新颖的理论方案，以通过使用同一电位来研究弱结合的核系统中的谐振水平。在此方案中，构建了一个新的电位，严格来说是具有原始浅孔电势的等光谱，并且具有更准确，更容易计算共振的特性。该方法的有效性已在其在中子富的同位素$^a $ c（$ \ equiv^{a-2} $ c+n+n）中的第一个$ 0^+$共振方面得到证明。
In this paper, a novel theoretical scheme is presented to investigate resonant levels in weakly bound nuclear systems by the use of isospectral potentials. In this scheme, a new potential is constructed which is strictly isospectral with the original shallow-well potential and has properties that are desirable to calculate resonances more accurately and easier. Effectiveness of the method has been had been demonstrated in terms of its application to the first $0^+$ resonances in the neutron-rich isotopes $^A$C ($\equiv ^{A-2}$C+n+n) in the three-body cluster model for A=18, 20.
