Yield Some Monte Carlo simulations have been done, without success. They’re needed for the calculation of the efficiency, the beam interception factor and the dead time corrections. In order to match ENDF-VII.0 data, a [beam factor x efficiency] = constant = 0.13 value has been assumed. ENDF-VII.0 data transformed in energies like tof_d=185.800m to tof_d=185.015m. Provisional neutron flux provided by Carlos Guerrero. 2004 resolution function. No dead time corrections.

Comments & conclusions A more carefully data reduction should be done, but it seems to have a “good quality”. Extra measurements at 100MHz, with 10us delay were done, in order to reach the thermal point. Some analysis has been tried, without success, at this moment.
