Resumen
Se bombardeó silicio con neutrones rápidos y se investigaron algunos de los productos resultantes, identificándose entre ellos Na 21 y Mg 28. El primero puede producirse por la reacción (n, 2p) o (n, He 3), o por ambas. La formación de Na 24 se puede atribuir a un proceso (n, χp); se prueba experimentalmente que la contribución de la captura de neutrones a la producción del isótopo de sodio es muy pobre. Se dan cálculos de energía relacionados con estas reacciones nucleares.
Silicon was bombarded with fast neutrons, and some of the resulting products were investigated, Na 21 and Mg 28 being identified among them. The former can be produced either by the reaction (n, 2p) or (n, He 3), or both. The formation of Na 24 can be attributed to an (n, χp) process; it is experimentally proved that the neutron capture contribution to the production of the sodium isotope is very poor. Energy computations related to these nuclear reactions are given.
