Abstract
Deals with the possibility of calculation of the preasymptotic charge density oscillation function. This function was given in a series form by Alfred and Van Ostenburgh (1969) and the coefficient of its first term may be determined from measurements. It is shown here that knowing the first coefficient, the so called asymptotic amplitude, one can express the subsequent amplitudes and phases in terms of muffin tin phase shifts corresponding to the matrix and impurity atoms. A calculation has been made for the case of an infinitely dilute CuZn alloy.
