摘要：
Fermilab experiment E835 has observed (p) over barp annihilation production of the charmonium state chi(c0) and its subsequent decay into pi(0)pi(0) and etaeta. Although the resonant amplitude is an order of magnitude smaller than that of the non-resonant continuum production of pi(0)pi(0), an enhanced interference signal is evident. A partial wave expansion is used to extract physics parameters. The amplitudes J = 0 and 2, of comparable strength, dominate the expansion.
