Abstract
The hard X-ray spectra of CuO and Cu2O have been measured at XANES(X-ray absorption near-edge structure) regions with a photo-acoustic detector using synchrotron radiation. It is shown that the information derived from XANES is also included in the X-ray photo-acoustic spectrum which reflects the heat production processes in those copper oxides. However, the results showed that the increases and the changes of the photoacoustic signal were different from those of the X-ray absorption coefficient at XANES regions.
