ANALYTICAL MICRO X-RAY FLUORESCENCE SPECTROMETER, W. Chang, J. Kerner, E. Franco, pp. 325-328

Monocapillary X-ray optics are a promising technology for producing intense microbeams of X rays.’ When coupled with laboratory X-ray sources, these optics are an enabling technology for the implementation of X-ray-based micro-spectrometer with spatial resolutions ranging from 1 to 25 microns. These instruments use X-ray fluorescence to determine the composition and thickness of materials with ...

and pp collisions 1 17 . FRAGMENTATION FUNCTIONS IN e + e − , ep AND pp COLLISIONS

The term ‘fragmentation functions’ is widely used for two related if conceptually different sets of functions describing final-state single particle energy distributions in hard scattering processes (see Refs. [1,2] for introductory reviews, and Refs. [3,4] for summaries of recent experimental and theoretical research in this field). The first are cross-section observables such as the functions...

Correlations Measured in 3 He ( e , e ′ pp ) n

Tensor correlations measured in 3He(e,e' pp)n.

We have measured the 3He(e,e' pp)n reaction at an incident energy of 4.7 GeV over a wide kinematic range. We identified spectator correlated pp and pn nucleon pairs by using kinematic cuts and measured their relative and total momentum distributions. This is the first measurement of the ratio of pp to pn pairs as a function of pair total momentum p(tot). For pair relative momenta between 0.3 an...

e+e− production from pp reactions at BEVALAC energies

We have performed a detailed study of dilepton production from pp collisions including the subthreshold ρ production via baryonic resonances (N(1520), N(1700)) in addition to the conventional dilepton sources as π0, η, ω and ∆ Dalitz decays and direct decays of vector mesons (ρ, ω). The role of baryonic resonances in ρ production from nucleon-nucleon collisions is studied in comparison to the D...
