Separation of spin and charge densities in La3NiO,j;,5 xvas investigated trsing Ratman scattering.lVIagnetic and electronic Ratnan scattering in La3Ni0j?,5 xvith 6 : 0.02 and 75 : 0.15 has 21 largecontintruut? below 1500 Clll '. As tetaaperattrre decreases to below 250 K at 75 : 0.15, the scatteringintensity below 650 Clll ' unoves into the high-energy range and siuaatrltaneottsly the intensity atthe energy of' the trndoped txvo-utastgnon joeak increases, as expected f'rotaa the separation of spinand char"e densities. Siraailar ef['ects are also observed even at the low carrier concentration of'6 = 0.02 beloxv 150 K. This indicates that the spin and charge densities separate even at the lowcarrier concentration of 75 = 0.02.
