框架光学势模型中的$^3_ηHe$原子核模拟

$^3_ηHe$ nucleus modeling in the frame optical potential model

V. A. Tryasuchev, A. V. Isaev

摘要:

本文研究了准束缚$η-^{3}$ He态的可能条件,并与有关$η$ N-散射长度的已有结果和文献中有关$^{3}$ He核的信息进行了比较。在光学势模型的框架下,不可能存在准束缚态$η-^{3}$ He态,但观测到的低能$η^{3}$ He相互作用异常是虚态.

英文摘要:

The conditions, at which quasi-bound $η-^{3}$He state is possible, have been investigated and compared with the available findings about $η$N-scattering length and the information about $^{3}$He nucleus from references. We conclud that the existence of quasi-bound $η-^{3}$He state within the framework of the optical potential model, which doesn`t contradict all collected findings, is not possible, but the observing anomaly of $η^{3}$He-interaction at low energies is a virtual state.
