"Measurement of ²³²Th(n,5nγ) cross sections from 29 MeV to 42 MeV";
European Physical Journal A, 50 (2014), 162; 1 - 8.

The excitation function of the reaction ²³²Th(n,5nγ)²²⁸Th from 29 to 42 MeV has been measured for the first time at the quasi-monoenergetic neutron beam of the UCL cyclotron CYCLONE employing the ⁷Li(p,n) source reaction. Taking advantage of the good energy resolution of the planar High-Purity Germanium (HPGe) detectors, prompt γ-ray spectroscopy was used to detect the γ-rays resulting from the decay of excited states of nuclei created by the (n,xn) reactions. The neutron beam was characterized by a combination of time of flight measurements carried out using a liquid scintillation detector and a ²³⁸U fission ionization chamber. Fluence measurements were performed using a proton recoil telescope. The results are compared with TALYS-1.4 code calculations.
