Abstract:	Two spin-doublet states in <SUB>Lambda</SUB><SUP>7</SUP>Li are studied on the basis of the alpha+Lambda+n+p four-body model. We employ the two-body interactions that reproduce the observed properties of any subsystems composed of alphaN,alphaLambda, alphaNN, and alphaLambdaN. Furthermore, the LambdaN interaction is adjusted so as to reproduce the 0<SUP>+</SUP>-1<SUP>+</SUP> splitting of in <SUB>Lambda</SUB><SUP>4</SUP>H. The calculated energy splittings of 3/2<SUP>+</SUP>-1/2<SUP>+</SUP> and 7/2<SUP>+</SUP>-5/2<SUP>+</SUP> states in <SUB>Lambda</SUB><SUP>7</SUP>Li are 0.69 and 0.46 MeV, which are in good agreement with the recent observed data. The spin-dependent components of the LambdaN interaction are discussed.
