Abstract

Using the multiple scattering approach (MSA) in the fixed center approximation we calculated the K^{− 4}He and K^{− 3}He scattering lengths. The K^{− 4}He scattering length is also analyzed in the optical potential model. Within the MSA the K^{− 3}He final state interaction factor was also calculated. It is found that the K^{− 3}He mass spectrum for the pd → ³HeK⁺ K⁻ reaction is expected to be influenced by the K^{− 3}He FSI effect.
