Several narrow resonance features in the system of two
K
S
mesons were found on the basis of experimental data obtained by using the 6-m spectrometer of the Institute of Theoretical
and Experimental Physics (ITEP, Moscow). Three resonances,
X(1070),
X(1545), and
f
J
(2220), are considered in the present study. An interference with the background is observed for the
X(1545) resonance. It is shown that
X(1070) and
f
J
(2220) resonances are produced under nearly identical kinematical conditions characterized by high transverse momenta and
the production of accompanying extra pions.
