Abstract: The electronic wave function in the slits is obtained by the Schrodinger equation,and electron diffraction wave function outside the slits by the strict solutions of path integral method.The diffraction intensity is proportional to the square of diffraction wave function.Then,the formula of electronic double-slit diffraction intensity can be obtained.It is found that the theoretical calculation result of quantum theory and the experimental measurement data tally pretty well.So,the method of quantum theory can explain electron diffraction phenomenon precisely.

Key words: Schrodinger equation, double-slit diffraction, path integral
