Resumen
The accurate calculations of neutron-induced reaction cross sections
are relevant for many nuclear applications. The photon strength functions and
nuclear level densities are essential inputs for such calculations. These quantities
for 235U are studied using the measurement of the gamma de-excitation
cascades in radiative capture on 234U with the Total Absorption Calorimeter at
n_TOF at CERN. This segmented 4π gamma calorimeter is designed to detect
gamma rays emitted from the nucleus with high efficiency. This experiment
provides information on gamma multiplicity and gamma spectra that can be
compared with numerical simulations. The code diceboxc is used to simulate
the gamma cascades while geant4 is used for the simulation of the interaction
of these gammas with the TAC materials. Available models and their parameters
are being tested using the present data. Some preliminary results of this
ongoing study are presented and discussed.
