摘要：

Precise four-body calculations for He-4(Lambda) and H-4(Lambda) have been performed in the framework of a variational method employing Jacobi-coordinate Gaussian-basis functions. All of the NNNLambda and NNNSigma rearrangements are explicitly taken into account for the first time in the context of realistic NN and YN interactions, The role of Lambda-Sigma conversion and the size of the virtual Sigma component in He-4(Lambda) and H-4(Lambda) are discussed.
