• Low energy K meson-nucleon interaction is re-investigated under the following assumptions. 1) K meson is scattered via KKππ interactions of the isospin independent and dependent type in addition to the direct K meson-hyperon-nucleon interactions. 2) In the low energy range (up to 250 Mev), S-wave K-nucleon scattering is dominant. 3) The source of S-wave K-mesons is extended to a comparable size as the potential range via the exchange of two pions. The characteristic features of low energy K-nucleon scattering are shown to be reproduced under the above assumptions. It turns out that the KKππ interaction of isospin dependent type plays an important role in K-nucleon scattering.
