So far we have demonstrated that the -ray coincidence method (the multiple -ray detection method) is a versatile method to achieve high resolution and high signal-to-noize ratio in nuclide determination. To extend this method we propose the X-ray coincidence method (the multiple X-ray detection method). We present a result of this method by using two low energy photon spectrometers and a standard -ray source of for activation of atoms. We could observe a peak in two dimensional X-ray matrix, which originates from coincidence of K-X and L-X rays. We demonstrated that background is reduced on the matrix.
