LAMBDA-PARTICLE ENERGIES FROM THE (PI(-NUCLEUS POTENTIAL(), K+) ASSOCIATED PRODUCTION REACTION ON NUCLEI AND THE STATE DEPENDENCE OF THE LAMBDA)

A LAMBDA-nucleus potential of the symmetrized Woods-Saxon type is main ly used and the LAMBDA-particle energies deduced from the (pi+, K+) as sociated production reaction on nuclei are analysed by a least-squares fitting. Although a firm quantitative conclusion about the state depe ndence of the LAMBDA-nucleus potential cannot be drawn on the basis of the existing data from the (pi+ , K+ ) process, it appears that this dependence is quite weak, as is also expected on the basis of other st udies. The present analysis indicates that the depth of the symmetrize d Woods-Saxon A-nucleus potential in the 1p state is somehow smaller t han the depth in the ls state, while the range of the potential is sli ghtly longer.
