We evaluate the contributions of final state interactions (FSI{close_quote}s) to J/{psi}{r_arrow}{rho}{pi} and {psi}{sup {prime}}{r_arrow}{rho}{pi} with various intermediate physical channels. We find that the rescattering of a{sub 2}{rho} and a{sub 1}{rho} into {rho}{pi} can change the {rho}{pi} production rate substantially, and, therefore, could be an explanation for the long-standing {open_quotes}{rho}{pi} puzzle.{close_quote}{close_quote} The FSI effects may also play a significant role for other channels, such as K{sup {asterisk}}{bar K} and f{sub 2}{omega}. {copyright} {ital 1997} {ital The American Physical Society}
