摘要

In the the framework of Regge phenomenology and meson-meson mass mixing; we estimated the masses of pseudoscalar meson nonet. The results suggest that the X(1835) should be assigned as the second radial excitation of the eta' rather than the ground pseudoscalar glueball. As a byproduct, we obtain the mass of ground pseudoscalar glueball in the glueball dominance picture. which is well agreement with predictions of other different theoretical models.
