英文摘要	Using a sample of 14x10(6) psi(2S) events accumulated with the BES II detector, evidence for f(0)(980)f(0)(980) production in chi(c0) decays is obtained for the first time; the branching ratio is determined to be B[chi(c0)-->f(0)(980)f(0)(980)-->pi(+)pi(-)pi(+)pi(-)]=[7.6+/-1.9 (stat)+/-1.6 (syst)]x10(-4). The significance of the f(0)(980) signal is about 4.6sigma.
