一个新的氘核有效势

A New Effective Potential for Deuteron

Taha Koohrokhi, Sehban Kartal

摘要:

我们首次在超对称量子力学的框架内解析地计算了氘核的静态性质。从超势出发,导出了一个新的有效势及其伙伴,使所有参数都能用实验数据拟合。给出了氘核波函数的解析表达式,明确地确定了正交$^{13}S_{1}$和$^{13}D_{1}$态的贡献.与一个π交换相比,超势产生一个静电以及两个π交换项。势的鞍点半径与波函数的最大值成线性比例。

英文摘要:

We calculate for the first time the static properties of the deuteron, within the framework of supersymmetric quantum mechanics, analytically. A new effective potential and its partner are derived from a superpotential so that all parameters are fitted by the experimental data. An analytical expression is obtained for the deuteron wave function and contributions of the orthogonal $^{13}S_{1}$ and $^{13}D_{1}$ states are determined, explicitly. Compared to one pion exchange, the superpotential produces an electrostatic as well as two pion exchange terms for the potential. The saddle point radius of the potential and the maximum of the wave function are linearly proportional.
