英文摘要	We propose a measurement of the elastic pi pi scattering phase-shift difference delta(0)(0)-delta(2)(0) through the psi(')-> j/psi pi(+)pi(-) process in the future high statistics bes-iii experiment. the decay amplitude is constructed with seven lorentz invariant form factors and is compared with their theoretical estimation. based on a monte carlo study, it is found that the phase-shift difference can be indeed recovered and, hence, it is expected to be measured in the energy region between 350 and 550 mev at future bes-iii.
