We estimate differential rapidity cross sections for J/Psi and Upsilon(1S) production via Cu-Cu and Au-Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC), and the relative probabilities of Psi'(2S) to J/Psi production via p-p collisions using our recent theory of mixed heavy-quark hybrids, in which the Psi'(2S) mesons have approximately equal normal q (q) over bar and hybrid q (q) over barg components. We also estimate the relative probabilities of Psi'(2S) to J/Psi production via Cu-Cu and Au-Au collisions, which will be measured in future RHIC experiments. We also review production ratios of Upsilon(2S) and Upsilon(3S) to Upsilon(1S) in comparison to recent experimental results. This is an extension of our recent work on p-p collisions for possible tests of the production of quark-gluon plasma via A-A collisions at RHIC.
