Abstract：
The density matrices of J/ψ produced in the non-polarized e ⁺－e ^－collisions in both experimental laboratory and helicity frame are discussed. The results show that rthe conclkusion for only J/ψ with the helicity ±1 having contributions to the procss is correct only in the experimental laboratory frame under some conditions. The number of the moments is the same and there is a simple relation between the moments in the two frames.
