In this work we deal with oscillations of neutral kaons appearing after the violation of flavour numbers by a mechanism outside of the weak interaction (W, Z^0 boson exchanges)-by the Kobayashi-Maskawa matrix. It is shown that the vacuum oscillation K^0 ←→K^0 will proceed without suppression with a mixing angle equal to π/4, while K1^0 ←→ K2^0 proceed with strong suppression, and in this case the mixing (i.e. the real K1^0 ←→ K2^0 transition) angle is determined by the angle Ө ≃0.0016 (these oscillations are the result of CP violation and overlapping of the mass distributions of these mesons ). The angle 6 of the CP violation measured experimentally is S = 0.00327 (6≃20). The mixing parameter of K1^0,K2^0 mesons may not coinside with the parameter of CP- violation and one must be careful.
