Résumé
Directional compton profile of zinc and Fe 0.25Ni0.75 have been measured with 60 KeV and 412KeV gamma-rays, and the results compared with the self consistent korring Kohn-Rostoker Coherent Potential Approximation for the iron nickel alloy.The other investigation reported all involve the use of the sybchrotron radiation; the polarisarion of synchrotron radiation has been estabilished for the SRS W9.4 line; for energies of the order of 50-65 KeV? and good agreements with the theoritical calculation werre obtained.Isotropic spin dependent compton profile of gadolinium and directional spin dependent compton profiles for nickel have been measured of synchrotron radiation.
