he generalized oscillator strength (GOS) of an atom plays the key role in the process of inelastic collisions of charged particles with atoms. Recently, Takayagi et al have obtained the GOS for the excitation of atomic krypton to the 4p5(2P1/2)5s and 4p5(2P3/2)5s states from inelastic-scattering measurements using electron-energy-loss spectroscopy. To examine the GOS for elctron-krypton collision in the squared-momentum-transfer in the range of 0.01 to 10 atomic units, calculations have been done by use of relativistic Slater local-density-potential equation. It has been found that the presnet results give an excellent agreement with the experimental measurement of Takayanagi et al.
