$η$介子与氦同位素形成准束缚态的可能性

The possibility of quasi-bound state formation of $η$-meson with helium isotopes

V. A. Tryasuchev, A. V. Isaev

摘要:

在光学势模型的框架下,找到了同位素$^{3}$ He,$^{4}$ He的$η$介子形成准束缚态的必要条件.这些条件已与氦核密度的结果和$η$ N-散射长度的可用信息进行了比较。因此,我们得出结论:在所讨论的模型$η-^{3}$的框架内,He准束缚态的形成是不可能的,但$η-^{4}$ He准束缚态的形成是可能的,并且具有很大的概率。

英文摘要:

The necessary conditions of quasi-bound state formation of $η$-meson with isotopes $^{3}$He, $^{4}$He have been found within the framework of optical potential model. These conditions have been compared with the findings about helium nucleus densities and with the available information about $η$N-scattering length. Thus, we have conclude that within the framework of discussed model $η-^{3}$He quasi-bound state formation is not possible, but $η-^{4}$He quasi-bound state formation is possible with the great probability.
