In this paper, to solve the current ambiguity in the entrance channels

or

of

resonance state for Kaon-proton interaction at 4.2 Gev/c, a mixture of transition matrix elements for entrance channels of

and

in the resonance formation of

have been used. A comparison of the theoretical invariant mass spectra with the totally Hemingway’s experimental data indicates that in this interaction, the

channel is the dominant entrance channel. In the following, using the

analysis method, the mass and width of the

resonant state are respectively obtained

and

that are in a good agreement with the present values of mass and width of the

in particle data group (PDG).
