Neutron differential elastic and inelastic scattering cross sections have been obtained for an incident neutron energy range between 8 and 14 MeV /sup 54/Fe, /sup 56/Fe, /sup 63/Cu and /sup 65/Cu. These measurements provide cross section data for nuclear fusion reaction design. Elastic scattering cross sections have been analyzed using a spherical optical model to obtain global parameters than can predict necessary neutron elastic scattering cross sections in the mass and energy ranges of the present work. The global parameters have been used to calculate the volume integral and the rms radius of the central real potential. The matter radii as well as the neutron radii then have been deduced. Coupled channels (CC) calculations were performed for elastic and inelastic scattering data assuming the harmonic vibrational model. The anharmonicity effect of the predictions of the cross section has been considered for /sup 56/Fe by inserting the reorientation matrix element in the CC calculations. Good fits have been obtained for both elastic and inelastic scattering cross sections of /sup 54/Fe and /sup 56/Fe. The quadrupole deformation parameters obtained are in good agreement with those deduced from Coulomb excitation measurements. The coupled channels calculations for /sup 63/Cu and /sup 65/Cu isotopes have been carried out using the weak particle-core coupling model. The quadrupole deformation parameters obtained are comparable with the corresponding deformations for the even core nuclei.
