    The paper is devoted to experimental investigation of receptivity of a Blasius boundary layer over a concave wall to surface non-uniformities. This receptivity mechanism is responsible for excitation of either unsteady or steady Görtler vortices by surface vibrations and roughness. As the result of this study quantitative receptivity characteristics are obtained, including the coefficients of the corresponding localized receptivity mechanism. These coefficients are obtained in Fourier space and are independent of the particular shape of the surface non-uniformities.
