摘要: Abstract The Λ-nucleus phenomenology, including the effective mass and small spin-orbit force, is shown to be consistent with Dirac phenomenology if couplings of σ ω mesons are motivated by quark model. This leads a tensor coupling meson Λ that equal magnitude but opposite sing vector so vector- scalar-field contributions potential cancel each other instead adding coherently as for nucleon.
