Keywords： partial wave analysis

Abundant ψ' events have been collected at the Beijing Electron Positron Collider-Ⅱ (BEPC Ⅱ) that could undoubtedly provide us with a great opportunity to study the more attractive charmonium decays. As has been noticed before, in the process of J/ψ decaying to the baryonic final states, pK-(∧), the evident A* and N* bands have been observed. Similarly, by using the product of χcJ from ψ' radiative decay, we may confirm this or find some extra new resonances. χc0's data samples will be more than χc1,2, taking into account the larger branching ratio of ψ'→γχc0. Here, we provide explicit partial wave analysis formulae for the very interesting channel ψ'→γχc0→γpK-(∧).
