Description

Spectra of inelastic scattering on samples of Cu64Zr36, Ni64Zr36 and Ni62Nb38 with isotopic substitution of Cu and Ni elements were measured. It is shown that partial spectra of more light-weight Ni and Cu atoms are displaced towards lower values of frequencies compared to the ones expected in the approximation of homogeneous force interaction in the system. The data obtained are in qualitative agreement with theoretically considered ones

Abstract (Russian)

Измерены спектры неупругого рассеяния нейтронов на образцах Cu64Zr36, Ni64Zr36 и Ni62Nb38 с изотопическим замещением элементов Cu и Ni. Показано, что парциальные спектры более легких атомов Ni и Cu смещены в сторону низких значений частот по сравнению с ожидаемым в приближении однородного силового взаимодействия в системе. Полученные данные находятся в качественном согласии с теоретическим рассмотрением
