By means of the electron energy loss spectroscopy(EELS), th e generalized oscillator strength density(GOSD) of krypton has been experimentally determined over a range 0.056K3.56 ato.unit and 8E88 eV, where K and E are momentum transfer and energy transfer respectively.The inci dent electron energy is 2.5 keV. As the function of momentum tansfer and energy transfer, the characteristic of the Bethe surface is analysed.
