Quasifree Scattering in the LITHIUM-6 (helium -3, HELIUM-3HELIUM-3) HYDROGEN-3 Reaction at E = 130 Mev.
Abstract
Experimental and theoretical cross-sections are studied for the ^6Li (^3 He, ^3He^3 He) ^3H quasifree scattering reaction at E_{rm inc} = 130 MeV and with angle pairs 20.0^circ -57.8^circ, 40.6 ^circ-40.6^circ , and 30.0^circ-50.4 ^circ. The theoretical cross -sections are calculated in the plane wave impulse approximation (PWIA) and with the three body model of Amado based on Faddeev equations. This model is made tractable by Ebenhoh and Haftel codes. In the three body model the trions, mass three nuclei, are treated as elementary particles with ^6Li being a ^3 He-^3H bound state. It is assumed that the trion-trion interaction can be represented by S wave separable potentials. Then the three body cross -sections are obtained with the Haftel-Ebenhoh code. In the past, PWIA predictions had problems, if not with the shapes, certainly with the magnitudes. The predicted quasifree enhancements have not agreed well with the experimental data. Therefore, the experimental cross -sections in this study are compared with both the PWIA and the three body predictions of the Haftel-Ebenhoh code.
