Abstract
The strong decays of the , , , , and as the quark-antiquark states are investigated in the framework of the meson decay model. It is found that the , , and appear to be the convincing states, while the assignment of the and as the isoscalar states is not favored by their widths. In the presence of the , , and being the members of the meson nonet, the mass of the kaon is phenomenologically determined to be about 2153 MeV. The width of this unobserved kaon is expected to be about 197 MeV in the decay model.
