Times Cited Count:184 Percentile:99.42(Physics, Nuclear)Transverse momentum distributions and yields for , and in collisions at = 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the RHIC. We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different collisions. We also present the scaling properties such as and scaling and discuss the mechanism of the particle production in collisions. The measured spectra are compared to next-to-leading order perturbative QCD calculations.

Times Cited Count:9 Percentile:52.86(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

The stability constants of Np(IV) with Ca and Si are measured by solubility method. In the case of coexistence of Ca or Si under high pH region, the solubility of tetravalent actinide was higher than the case of without Ca or Si in a recent study. However, in the case of Np(IV), the experiment was not measured. Therefore, the solubility of Np(IV) was measured with Ca or Si in the high pH region, the stability constants of (CaNp(OH)) and Si of Ca and the Np and complex (Np(OH)nSiO(OH) etc) was calculated by solubility of Np(IV).
