Resumen
Se encontró una nueva actividad de rodio de 117 minutos de vida media que se forma por reacción (n, p) (n, α) y (d, α) pero no como un producto de fisión normal o como un hijo del Ru-106. La energía máxima de los negatrones emitidos es de 0,7 MeV. La energía de desintegración total Q es de unos 3,6 MeV. El número de masa de la nueva actividad de rodio es 106, probablemente un isómero superior al conocido Rh-106 de 30 segundos. El Rh-106 recién encontrado no se desintegra por rayos gamma al estado normal de Rh-106. Emite los mismos rayos gamma a los 30 segundos Rh-106 y Ag-106 así como otras líneas gamma.
A new rhodium activity of 117 minutes half-life was found which is formed by (n, p) (n, α) and (d, α) reaction bat not as a normal fission product or as a daughter of Ru-106. The maximum energy of the negatrons emitted is 0.7 MeV. The total disintegration energy Q is about 3,6 MeV. The mass number of the new rhodium activity is 106, probably a higher isomer of the known 30 seconds Rh-106. The newly found Rh-106 does not disintegrate by gamma ray to the normal state of Rh-106. It emits the same gamma rays at the 30 seconds Rh-106 and the Ag-106 as well as other gamma lines.
