We report an analysis of the nuclear dependence of the yield of Drell-Yan dimuons from the 800 GeV/c proton bombardment of 2H, C, Ca, Fe, and W targets. Employing a new formulation of the Drell-Yan process in the rest frame of the nucleus, this analysis examines the effect of initial-state energy loss and shadowing on the nuclear-dependence ratios versus… (More)
After evaluation of several modern object-oriented methods for development of the computing systems for the PHENIX detector at RHIC, we selected the Shlaer-Mellor Object-Oriented Analysis and Recursive Design method as the most appropriate for the needs and development environment of a large nuclear or high energy physics detector. This paper discusses our… (More)
X-Ray powder diffraction studies have been used to measure the thermal expansion properties of three zeolites with the LTA topology and provide details of the underlying structural changes. Siliceous ITQ-29 and dehydrated and hydrated silver zeolite A have large negative, moderate negative and positive thermal expansion coefficients, respectively.
