The intrinsic Mn 2p1/2,3/2, K 2p1/2,3/2 and O 1s spectra for KMnO4 were obtained from a sample in situ fractured in an ultra-high vacuum. In order to obtain the primary excitation Mn 2p spectrum from the observed Mn 2p spectrum, the K 2p and O 1s spectra were used as response functions for the Fourier transform deconvolution method. Firstly, the K 2p1/2,3/2 spectrum was divided into two components, 2p1/2 and 2p3/2, by the deconvolution method. The obtained K 2p response-function spectrum had a smaller intensity ratio of the inelastic to non-energy loss parts than did the O 1s. However, the loss energies of four peaks in the K 2p spectrum coincided with those in O 1s spectrum. Neglecting the noise and small peaks, the spectral profiles of the Mn 2p spectra deconvoluted by the K 2p and O 1s spectra agreed. The spectra had no satellite peaks.
