note = {The in-depth distribution of residual stresses in shot-peened steels was measured by using high energy X-rays from a synchrotron radiation source. The relation between the 2θ and sin^2Ψ was obtained with the side-inclination method (Ψ diffractometer). The distribution of residual stresses was first evaluated by the nonlinearity of the sin^2Ψ diagram by a simplex method. The estimated stress agreed with the distribution determined through the sin^2Ψ method by using Cr-Kα radiation combined with the conventional surface removal method. A new method was proposed to estimate the stress value of the distributed residual stress. The new method was a combination of the side-inclination method and the iso-inclination method (ω diffractometer) to maintain the penetration depth constant. The sin^2Ψ diagram could be approximated by the linear relationship. The evaluated stress distribution agreed well with the distribution obtained by the surface removal method.},
