Charged-particle spectra associated with direct photon (γ dir) and π 0 are measured in p+p and Au+Au collisions at center-of-mass energy √ s N N = 200 GeV with the STAR detector at RHIC. A shower-shape analysis is used to partially discriminate between γ dir and π 0. Assuming no associated charged particles in the γ dir direction (near side) and small(More)

We have systematically calculated the ground state geometries, relative stability, electronic structure, and spectroscopic properties of PtCl(n) (n = 1-7) clusters. The bonding in these clusters is dominated by covalent interaction. In neutral clusters, chlorine atoms are chemically bound to Pt up to n = 5. However, in neutral PtCl(6) and PtCl(7) clusters,(More)
