Descrição: We report on K*{sup 0} production at midrapidity in Au + Au and Cu + Cu collisions at {radical}(s{sub NN})=62.4 and 200 GeV collected by the Solenoid Tracker at the Relativistic Heavy Ion Collider detector. The K*{sup 0} is reconstructed via the hadronic decays K*{sup 0}{yields}K{sup +}{pi}{sup -} and K*{sup 0}{yields}K{sup -}{pi}{sup +}. Transverse momentum, p{sub T}, spectra are measured over a range of p{sub T} extending from 0.2 GeV/c up to 5 GeV/c. The center-of-mass energy and system size dependence of the rapidity density, dN/dy, and the average transverse momentum, , are presented. The measured N(K*{sup 0})/N(K) and N({phi})/N(K*{sup 0}) ratios favor the dominance of rescattering of decay daughters of K*{sup 0} over the hadronic regeneration for the K*{sup 0} production. In the intermediate p{sub T} region (2.0
