Coincidence measurements with high energy electrons

Autor: J. S. O'Connell

Publikováno v: From Collective States to Quarks in Nuclei ISBN: 9783540105701

The potential for A(e,e'x) measurements is beginning to be critically examined. Nuclear disintegration by electrons and photons shares many of the problems of interpretation found in reactions induced by hadronic projectiles. These theoretical diffic

Phenomenological Δ-nucleus potential from inclusive electron-nucleus scattering data

Autor: J. S. O'Connell, R. M. Sealock

Publikováno v: Physical Review C. 42:2290-2294

The four-momentum-transfer dependences of the quasielastic and \ensuremath{\Delta} peak positions seen in electron-nucleus scattering are interpreted in terms of momentum-dependent potentials. We have used data on the \ensuremath{\Delta} peak positio

The coincident electrofission ({ital e},{ital e}{prime}{ital f}) cross sections of {sup 233,238}U were measured in the excitation range 150--550 MeV. The probability of fission was found to be near unity in the delta resonance region (250--550 MeV),

Photopion production in the Fermi-gas model

Autor: E.T. Dressler, J. S. O'Connell, W.M. MacDonald

Publikováno v: Physical Review C. 19:455-464

In order to understand some of the general properties of pion photoproduction from a nucleus, we have studied the photoproduction process from a Fermi gas. In this calculation, we used the non-relativistic pion photoproduction operator of Blomqvist a

Electrodisintegration ofHe3

Autor: S. P. Fivozinsky, P.T. Kan, G. A. Peterson, J. W. Lightbody, J. S. O'Connell, S. Penner, Z.M. Szalata, D. V. Webb

Publikováno v: Physical Review C. 12:1118-1125

The continuum spectra of $^{3}\mathrm{He}$ have been measured up to excitation energies of 40 MeV by means of inelastic electron scattering. Incident electron beam energies between 60 and 120 MeV were used, corresponding to a momentum transfer range

Properties of the charged photopion production operator and theH2(γ,π+)2ncross section

Autor: W.M. MacDonald, J. S. O'Connell, E.T. Dressler

Publikováno v: Physical Review C. 20:267-272

Threshold photopion production from the proton and the deuteron is calculated with the ..gamma..N..pi.. amplitudes of Blomqvist and Laget. The epsilon-circumflexxsigma-arrow-right operator is found to dominate both cross sections up to 60 MeV above t
