    "abstract": "We present predictions for the the K^- \\alpha scattering length obtained\nwithin the framework of the multiple scattering approach. Evaluating the pole\nposition of the K^- \\alpha scattering amplitude within the zero range\napproximation, we find a loosely bound K^- \\alpha state with a binding energy\nof E_R = -2 ... -7 MeV and a width \\Gamma_R = 11 ... 18 MeV. We propose to\nmeasure the K^- \\alpha scattering length through the final state interaction\nbetween the \\alpha and K^- meson produced in the reaction dd \\to \\alpha K^+\nK^-. It is found that the K^-\\alpha invariant mass distribution from this\nreaction at energies near the threshold provides a new tool to determine the\ns-wave K^- \\alpha scattering length.",
