Abstract
Se discute la influencia de las reacciones umbral, inducidas por la componente rápida del espectro neutrónico, en el análisis por activación en reactores nucleares. Se describen ejemplos
de su importancia analítica. Se reseña el estado actual de los datos de secciones eficaces
de reacciones umbral publicados en la literatura. Se discuten la disponibilidad y la validez de
estos datos, sobre la base de su trazabilidad y su consistencia.
The influence of the threshold reactions, induced by the fast component of the neutron spec- trum, in nuclear reactor activation analysis, is discussed. Some examples of their analytical im- portance are described. The present status of the cross-section data of the threshold reactions published in the literature is reviewed. The availability and the validity of these data, on the basis of their traceability and consistency, are discussed.
