Abstract
The γ-rays following the neutron capture on 240Pu and 244Cm has been measured at the n_TOF facility at CERN with the Total Absorption Calorimeter (TAC) and with C6D6 organic scintillators. The TAC (Total Absorption Calorimeter) is made of 40 BaF2 crystals operating in coincidence and covering 95% of the solid angle. This allows to obtain information concerning the energy spectra and the multiplicity of the γ-ray cascades. Additional information is also obtained from the C6D6 detectors, were the energy deposited spectra can be obtained. We have analyzed the measured data in order to draw conclusions about the Photon Strength Functions (PSFs) of 241Pu and 245Cm. The analysis has been performed fitting the PSFs to the experimental results in order to find neutron capture cascades capable of reproducing at the same time a great variety of deposited energy spectra. These cascades will be also used to make corrections in the capture cross section measurement of 244Cm.
