Interactions of π -mesons of kinetic energy 915 Mev with carbon nuclei

Abstract

Las interacciones de los mesones u con núcleos de carbono se estudiaron con una cámara de burbujas de propano. Se encontró que la sección transversal total del carbono era (383 = 20) mb de los cuales (89 ± 12) mb correspondían a dispersión elástica. Se hace una descripción detallada de los eventos con reemisión de un π. La distribución angular de dispersión de difracción y la sección transversal total obtenida se describieron mediante un modelo óptico utilizando un potencial gaussiano imaginario. El radio r.m.s. distribución de carga eléctrica.

Interactions of u- mesons with carbon nuclei were studied with a propane bubble chamber. The total cross-section on carbon was found to be (383 =20) mb of which (89 ± 12) mb corresponded to elastic scattering. A detailed description of the events with re-emission of a π is made. The diffraction scattering angular distribution and the total cross-section obtained were described by an optical model using an imaginary gaussian potential, The r.m.s, radius of this potential obtained was 3.0 -10 13 cm, which is considerably greater than the corresponding radius obtained for the electric charge distribution.
