Description
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 the conclusion for only J/ψ with the helicity +-1 having contributions to the process 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
