Show affiliationsEpithermal and thermal flux parameters for the thermal flux density standard at the National Research Council have been measured to allow a more accurate calculation of activation rates. The epithermal spectrum is found to follow a E-0.95 law, where E is the neutron energy. The effective neutron temperature in the irradiation cavity is found to be 42 °C which is 22 °C higher than the moderator temperature. A formula to calculate the reaction rate is given.
