The reaction p p -> p p pi+ pi- at 7.9 BeV/c
The reaction p p -> p p pi+ pi- has been studied at an incident momentum of 7.9 BeV/c using the Brookhaven 80 inch hydrogen bubble chamber. App'roximate1y 3600 events of the 'reaction were identified; the cross section was determined to be 2.54 +/- .13 mb. The reaction is found to be dominated by …

Dipyrazolylphosphanes in Condensation and P–N/P–P Bond Metathesis Reactions
Phosphorus plays a crucial role in modern p-block chemistry.1 One reason for that is the diagonal relationship between phosphorus and carbon.2 Comparable to carbon and its chemistry, phosphorus tends to form homoatomic bonds, which is explainable by the relatively high P–P single bond energy (ca. …

On P-Radical P-Blocks of Group Algebras
p-Radical p-blocks of finite group algebras are studied. Much of the p-radical group theory is generalized to p-blocks through R. Knorr's work on simple induction and restriction pairs. In addition, several results concerning such blocks are proved.

p-arithmetic cohomology and p-adic automorphic forms
The cohomology of an arithmetic group with coefficients in finite-dimensional representations can be described in terms of automorphic representations of the group. In this thesis, we prove similar results for the cohomology of an *S*-arithmetic groups (where *S* is a finite set of primes) with …

Synthesis and catalytic evaluation of chiral ferrocenyl p^p and p^n palladium(II) complexes
Chapter 2 outlines initial attempts made to synthesize analogues of the P,N-type chiral ligands (η5-C5H5)Fe(η5-C5H3-PPh2)C*H(OH)(3,5-R2pz) R = H SPNa and R = Me SPNb first prepared by Togni, and the P,P-type chiral ligands (η5-C5H5)Fe(η5-C5H3-PR2)C*H(OH)(PPh2) R = Ph SPPa, R = i-Pr SPPb of the …

Niobium-mediated generation of P-P multiply bonded intermediates
The diphosphaazide complex (MesNPP)Nb(N[CH2 tBu]Ar)3, 1 (Mes = 2,4,6-tri-tert-butylphenyl, Ar = 3,5-dimethylphenyl), releases a P2 unit upon heating to form MesNNb(N[CH2 tBu]Ar)3, 2, in a first-order process. The chemistry of the putative P2 intermediate was probed with a variety of reagents. It …

Elastic-Wave Imaging Using P-P, Sh-Sh, and Sv-P Events: Modeling and Data Processing
This thesis focuses on using seismic data that were generated by a vertical vibrator and recorded by a vertical geophone to build two different subsurface images: a conventional P-P section and a converted-wave SV-P section. Radiation patterns are calculated based on Miller and Pursey’s equations …

A Measurement of the Reactions (Bar)p/p Going to Eta/eta, (Bar)p/p Going to Pi(0)/eta and (Bar)p/p Going to Pi(0)/pi(0) From 1.188 GeV/c to 1.445 GeV/c
The reactions p&d1;p→hh→4g ,p&d1;p→p 0h→4g and p&d1;p→p0p 0→4g were investigated at incident antiproton momenta between 1.188 and 1.445 GeV/c using the Low Energy Antiproton Ring (LEAR) at CERN. This investigation was part of an overall program searching for exotic …

Synthesis and characterization of ruthenium complexes with (N-N)(P-P) and (N-P)2 donor sets
Since the discovery of nonlinear effects, both the theory and measurement techniques have been developed significantly, especially since the invention of the laser. However, structure-NLO property relationships for organometallics as well as their NLO mechanisms are far less explored than those of …

High energy photoproduction of the p and p' vector mesons
In an experiment in the broad band photon beam at Fermilab we observe diffractive production of 21T =and 41T =states from Be, AI. Cu and Pb targets. The 21T=data is dominated by the p(770) and the 41T=is dominated by the p'(1500). We measure the energy dependence of p photoproduction from Be and …
