dc.description.abstract	Electrical resistivity measurements on compounds belonging to CeSi(2-x)Ga(x) (0.7 less than or equal to x less than or equal to 1.3) have been performed. The samples in this concentration range show a smooth crossover from a RKKY dominated ground state to a state where the single site Kondo interactions dominate. The variation of Kondo temperature and the magnetic ordering temperature with Ga concentration agree well with the Kondo lattice model. An attempt has also been made to calculate the resistivity curves in these compounds from our quasielastic neutron line width data and using Freimuth's model modified by Garde and Ray. Our results remove an important deficiency in the tatter model concerning the motion of the f level relative to the Fermi level.	en_US
