The earliest DT nuclear fusion discoveries

M. B. Chadwick, G. M. Hale, M. W. Paris +6

We describe the earliest measurements of the DT fusion cross section commissioned by the Manhattan Project, first at Purdue University in 1943 and then at Los Alamos 1945-6 and lat…

First Precision Measurement of the Parity Violating Asymmetry in Cold Neutron Capture on He

n3He Collaboration, M. T. Gericke, S. Baeßler +26

We report the first precision measurement of the parity-violating asymmetry in the direction of proton emission with respect to the neutron spin, in the reaction $^{3}\mathrm{He}(\…

The nHe Experiment: Parity Violation in Polarized Neutron Capture on He

n3He Collaboration, M. McCrea, M. L. Kabir +26

Significant progress has been made to experimentally determine a complete set of the parity-violating (PV) weak-interaction amplitudes between nucleons. In this paper we describe t…

Monotonic properties of the shift and penetration factors

Carl R. Brune, Gerald M. Hale, Mark W. Paris

We study derivatives of the shift and penetration factors of collision theory with respect to energy, angular momentum, and charge. Definitive results for the signs of these deriva…

R-Matrix description of particle energy spectra produced by low-energy T+T reactions

C. R. Brune, J. A. Caggiano, D. B. Sayre +3

An R-matrix model for three-body final states is presented and applied to a recent measurement of the neutron energy spectrum from the T+T->2n+alpha reaction. The calculation inclu…

Effective field theory as a limit of R-matrix theory for light nuclear reactions

Gerald M. Hale, Lowell S. Brown, Mark W. Paris

We study the zero channel radius limit of Wigner's R-matrix theory for two cases, and show that it corresponds to non-relativistic effective quantum field theory. We begin with the…
