S. Bayegan, M. Harzchi, M. A. Shalchi

摘要:

在三维动量-螺旋度表象中,低动量有效相互作用$V_{low k}$被表示为动量矢量大小和动量矢量夹角的函数。作为应用,在Lee-Suzuki方法的模型空间中使用了AV 18势,证明了低动量有效相互作用$V_{low k}$再现了由裸势$V_{NN}$得到的相同的两体观测值。

英文摘要:

The low-momentum effective interaction $V_{low k}$ has been formulated in the three-dimensional momentum-helicity representation as a function of the magnitude of momentum vectors and the angle between them. As an application, AV18 potential has been used in the model space of Lee-Suzuki method and it has been shown that the low-momentum effective interaction, $V_{low k}$ reproduces the same two-body observables obtained by the bare potential $V_{NN}$.
