Neutron elastic scattering at $$\varvec{30.8}$$ MeV on $$\varvec{^{\text {nat}}\textrm{Ce}}$$
Abstract Elastic scattering of fast neutrons at an incident energy of 30.8 MeV on a natural cerium target was measured during an experiment conducted at the Neutrons For Science facility at GANIL-SPIRAL2. This is the first measurement on cerium using incident neutron energy above 20 MeV. The differential cross-section up to 40 $$^\circ $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mmultiscripts> <mml:mrow/> <mml:mrow/> <mml:mo>∘</mml:mo> </mml:mmultiscripts> </mml:math> in the centre-of-mass frame was extracted using the MONSTER liquid scintillator array for the scattered neutron detection. The experimental results are compared to global optical-model calculations, providing an overall very good agreement and a useful benchmark at intermediate energy.
