Abstract
Fermilab experiment E835 has studied reactions pp{yields}{pi}{sup 0}{pi}{sup 0},{pi}{sup 0}{eta},{eta}{eta}, {pi}{sup 0}{eta}{sup '} and {eta}{eta}{sup '} in the energy region of the {chi}{sub c0}(1{sup 3}P{sub 0}) from 3340 MeV to 3470 MeV. Interference between resonant and continuum production is observed in the {pi}{sup 0}{pi}{sup 0} and {eta}{eta} channels, and the product of the input and output branching fractions is measured. Limits on resonant production are set for the {pi}{sup 0}{eta} and {pi}{sup 0}{eta}{sup '} channels. An indication of interference is observed in the {eta}{eta}{sup '} channel. The technique for extracting resonance parameters in an environment dominated by continuum production is described.
