The low-energy LAMBDA -nucleon interaction was represented by several effective central potentials that have a hard core of radius 0.4 F and four- parameter attractive wells with an interaction for large separations suggested by the two-pion-exchange mechanism. These potentials, which are consistent with the binding-energy data for the light hypernuclei, were taken to represent the LAMBDA -nucleon interaction in even-parity states for energetic greater than those that play a role in the binding of the light hypernuclei. These potentials and others of reduced strength were taken to represent the interaction in odd- parity states. The binding energy D of all particle in nuclear matter and LAMBDA -nucleon scattering cross sections were calculated with these potentials. The calculated cross sections and empirical cross sections for energies less than 76 Mev in the zero-momentum frame are in agreement only if the interaction of odd- parity states is taken to be (approximately) as strong as that in even -parity states. These effective central potentials of equal strength in evenparity and odd-parity states lead to values of D close to 40 Mev. (auth)
