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.

Times Cited Count:9 Percentile:52.49(Physics, Multidisciplinary)Pressure phase diagram of the antiferromagnet UIn3 was constructed from the electrical resistivity measurement under high pressures up to 9 GPa. Neel temperature increases monotonically with increasing pressure from 88 K at ambient pressure to 127 K at 9 GPa. We observed an additional resistive anomaly at 21 K under 1.4 GPa. This anomaly brings about an increase of the residual resistivity. The transition temperature decreases gradually with increasing pressure and disappears around 8 GPa.

Times Cited Count:51 Percentile:87.91(Materials Science, Multidisciplinary)The pressure effect on the lattice constant of NiO with the rhombohedral distorted B1 structure was studied up to 141 GPa by angle-dispersive x-ray diffraction using synchrotron radiation, an imaging plate, and a diamond anvil cell. The lattice constant and , expressed in the hexagonal lattice, decrease monotonously with increasing pressure. The axial rage decreases monotonously with increasing pressure, indicating the distortion in the rhombohedral [111] direction becomes larger as pressure increases. The signiifcant change of above 60 GPa, suggested by a recent theoretical calculation, was not observed.

The pressure effect on the lattice constant of NiO with the rhombohedral distorted B1 structure was studied up to 141 GPa by angle-dispersive x-ray diffraction using synchrotron radiation and an imaging plate, with reference to a recent theoretical calculation within the density-functional formalism with the local-spin density approcximation. The lattice constant and , expressed in the hexagonal lattice, decrease monotonously with increasing pressure. The axial rage decreases monotonously with increasing pressure, indicating the enhancement of the rhombohedral distortion. The signiifcant change of above 60 GPa suggested by the calculation was not observed.
