Large Momentum Transfer Measurements of the Deuteron Elastic Structure Function A(Q^2) at Jefferson Laboratory

The Jefferson Lab Hall A Collaboration, L. C Alexa

The deuteron elastic structure function A(Q^2) has been extracted in the Q^2 range 0.7 to 6.0 (GeV/c)^2 from cross section measurements of elastic electron-deuteron scattering in c…

Pion and photon couplings of N* resonances from scattering on the proton

A. Yu. Korchin, O. Scholten, R. G. E. Timmermans

Results of a relativistic model for pion- and photon-induced reactions on the proton are presented. The model is crossing symmetric and gauge invariant. The nucleon resonances P_11…

Observation of a Coherence Length Effect in Exclusive Rho^0 Electroproduction

K. Ackerstaff

Exclusive incoherent electroproduction of the rho^0(770) meson from 1H, 2H, 3He, and 14N targets has been studied by the HERMES experiment at squared four-momentum transfer Q**2>0.…

Dynamical models of NGC 3115

Eric Emsellem, Herwig Dejonghe, Roland Bacon

We present new dynamical models of the S0 galaxy N3115, making use of the available published photometry and kinematics as well as of two-dimensional TIGER spectrography. We first…

The Three-Dimensional Mass Distribution in NGC 1700

Thomas S. Statler, Herwig Dejonghe, Tammy Smecker-Hane

A variety of modeling techniques is used with surface photometry from the literature and recently acquired high-accuracy stellar kinematic data to constrain the three-dimensional m…

Production of e+e- pairs in proton-deuteron capture to 3He

A. Yu. Korchin, D. Van Neck, M. Waroquier +2

The process p+d \leftrightarrow 3He + γ* at intermediate energies is described using a covariant and gauge-invariant model, and a realistic pd3He vertex. Both photodisintegration o…
