Abstract
The $\phi\pi^+\pi^-$ production in $p\bar{p}$ annihilation at rest is strongly enhanced by a two step mechanism with intermediate $K\bar{K}\pi\pi$states. The relative yield of the $\phi$ production due to the resonant final state interaction decreases with increasing total energy of the $p\bar{p}$system.
