Abstract

• The purpose of this research is to investigate the structure of η-mesic oxygen nucleus theoretically which is a bound system of η-meson and Oxygen core nucleus. Since original functional form of η-N interaction cannot be analytically solved, we have transformed the functional form into Gaussian form by applying the Gauss elimination method. The transformed η-N potentials are equivalent to that of original potential by using the optimum sets, μ1 =0.05 fm,μ N =20 fm and N=20. The η-nucleus interaction is obtained by folding the η-N interaction with Oxygen nucleus nuclear density. By applying the η-nucleus folding potential we have computed the binding energy of O 16 η system which is 3.2814 MeV and its level width is 0.3704 MeV.
