Resumen
Se han obtenido secciones transversales diferenciales absolutas para la dispersión elástica de partículas alfa del helio a 36,8, 38,8, 40,8, 41,9, 44,4, 46,1, 47,1 y 47,3 Mev. Las mediciones se han realizado a intervalos de 2 grados en un rango angular desde aproximadamente 15 grados hasta más de 90 grados en el centro del sistema de masas. La distribución angular muestra un único mínimo a 65 grados en las dos energías más bajas, y dos mínimos, a unos 35 y 70 grados, en las otras energías.
Absolute differential cross sections for the elastic scattering of alpha particles from helium have been obtained at 36.8, 38.8, 40.8, 41.9, 44.4, 46.1, 47.1, and 47.3 Mev. Measurements have been made at intervals of 2 degrees over an angular range from about 15 deg to beyond 90 deg in the center of mass system. The angular distribution shows a single minimum at 65 deg at the two lowest energies, and two minima, at about 35 and 70 deg, at the other energies.
