When pure deuterium is used as the filling gas, the data can be adjusted to a Gaussianfunction, related to anisotropic emission, superposed on a constant pedestal, related to isotropic emission.

The neutron flux at these two angles are used, along with the angulardistribution obtained from the track detectors, in order to estimate the absolute neutron yield of both the isotropic and the anisotropiccontributions. From examining different groups of shots, it is found that the shape of the angular distribution is important in the estimationof anisotropy, and that the value usually reported, as the ratio of the neutron flux head on and side on, as measured by activation counters,may be misleading. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57066314 https://www.redalyc.org/journal/570/57066314/ https://www.redalyc.org/journal/570/57066314/html/ https://www.redalyc.org/journal/570/57066314/57066314.epub https://www.redalyc.org/journal/570/57066314/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
