英文摘要	The K+ scattering cross section with the in-medium virtual pion is evaluated in the lowest-order chiral perturbation theory with the density-dependent pion decay constant and mass. The contribution of nuclear pions to the total K+-nucleus cross section is found to be about 5% and 12% when the excess pion numbers per nucleon n(pi) = 0.057 and 0.13 are used. The inclusion of the off-mass-shell behavior of the K(+)pi amplitude produced a significant improvement in the K+-nucleus cross section.
