We examine a recently published calculation which predicts an oscillatory
behaviour for the decay of Lambdas produced together with a neutral kaon, and
proposes a new expression for the wavelength of kaon strangeness oscillations.
We modify the calculation by imposing the requirement that the interference of
the K_L and K_S components of the kaon wave function occurs at a specific
space-time point. With this requirement, the unusual results predicted vanish,
and the conventional results are recovered.Comment: 9 pages Latex, no figures. Added Latex section omitted befor
