K原子能移和宽度的唯象分析(英文)

Phenomenological Analysis of Energy Shifts and Widths of Kaonic Atoms

尝试用WoodsSaxon形式的光学势来分析K原子,通过拟合一系列K原子数据,得到了一套最佳光学势参数.把得到的这套光学势和前人的其他几种光学势在接近核表面处作了比较,发现它们彼此符合得很好.另外,与核子-核势相比较,对于虚部势,K核的WoodsSaxon势与核子-核的很相似,但是对于实部,K核势要更深更窄一些.

We analyze kaonic atoms in terms of the phenomenological optical potential of Woods-Saxon form. By fitting data of kannic atoms, we obtain an optimal set of optical potential parameters. Comparing this optical potential near surface of nucleus with other optical potentials obtained in some successful research works, we find that they are in rather good agreement with each other. On the other hand, the imaginary part of our potential between kaon and nucleus is similar to that between nucleon and nucleus, but the real part of the potential between kaon and nucleus is much deeper and narrower in radial distribution.
