Search for an antimony isotope with a 30 days half-life

Abstract

Varios autores han informado sobre un isótopo de producto de fisión de antimonio que se desintegra con una vida media de alrededor de 30 días. Como en trabajos anteriores en nuestro laboratorio con los isótopos pesados de antimonio nunca habíamos observado una vida media semejante, se realizaron algunos experimentos para determinar su existencia y propiedades nucleares.A fission product isotope of antimony which decays with a half-life around 30 days has been reported by several authors. As in previous work at our laboratory with the heavy isotopes of antimony we had never observed such a half-life, some experiments were performed to determine its existence and nuclear properties.
