Differential cross sections and generalized oscillator strengths have been measured for two optically allowed transitions 2[ital p][sup 6]([sup 1][ital S][sub 0])[r arrow]2[ital p][sup 5]([sup 2][ital P][sub 1/2,3/2])3[ital s] and the optically forbidden transition 2[ital p][sup 6]([sup 1][ital S][sub 0])[r arrow]2[ital p][sup 5]([sup 2][ital P][sub 1/2])3[ital p] in Ne. These measurements are carried out for electron kinetic energies 300, 400, and 500 eV at small scattering angles ([theta]=2.4[degree]--33.7[degree]) by means of electron-energy-loss spectroscopy. Optical oscillator strengths have been determined by extrapolating the generalized oscillator strengths to zero momentum transfer, as (0.137[plus minus]0.018) and (0.0106[plus minus]0.0014), for the 2[ital p][sup 5]([sup 2][ital P][sub 1/2])3[ital s] and 2[ital p][sup 5]([sup 2][ital P][sub 3/2])3[ital s] states, respectively. Integrated cross sections have been calculated by integrating the differential cross sections for each impact energy. The errrors are estimated to be less than 13%.
