Abstract The energy and angular distribution of theα-particles from the50Cr(n, α) reaction for 14.1 MeV incident neutron energy was measured by means of a multitelescope system. The results are compared with calculations based on the statistical model of nuclear reactions including precompound processes. This comparison indicates that there is somewhat more emission of high energyα-particles than predicted from the conventional precompound model suggesting direct excitation of the lowest excited states of47Ti. No indication is found for a reduction of the effective moment of inertia below the rigid body value. From the shape of theα-spectrum in the backward hemisphere and the known total number of levels below (U=3 MeV the level density parameters of47Ti were determined asa=5.4±0.3 MeV−1 andΔ=−1.9±0.2 MeV in the framework of the back-shifted Fermi-Gas model.
