Abstract
The partial-wave states 1{sup +}SO+(K*{pi}) and 1{sup +}SO+SO+({rho}K) of K{pi}{pi} system diffractively produced by K-meson in nuclei have been described in the framework of K-matrix model. The production of the two 1{sup +} resonances Q{sub a}(1400) and Q{sub b}(1300) in the processes under investigation and nonresonant term. The model includes the direct resonant production and nonresonant term. The relative contribution of the Q-resonances into cross section of 1{sup +}SO+ production has been found to be equal 0.57. The SU(3) analysis of these resonant states shows that they are mixtures of the SU(3) nonet states with J{sup pc}=1{sup ++} and J{sup pc}=1{sup +-}. The partial coupling of Q{sub b} have been used to predict the masses and partial widths constants of another members of nonets. 10 refs.; 1 fig.
