Elements of X-ray Diffraction
Prentice Hall, 2001 - Technology & Engineering - 664 pages
Intended to acquaint the reader with the theory of x-ray diffraction, the experimental methods involved, and the main applications. The book is a collection of principles and methods stressing X-ray diffraction rather than metallurgy. KEY TOPICS: The book is written entirely in terms of the Bragg law and can be read without any knowledge of the reciprocal lattice. It is divided into three main parts--Fundamentals; experimental methods; and applications. MARKET: Designed for beginners, not as a reference tool for the advanced reader.

A constant charge is thus added to the capacitor for each pulse received and this
charge leaks away through the resistor until , at equilibrium , the rate of addition
of charge is just balanced by the rate of leakage . The rate of charge leakage is ...

time constants are used with the higher scales , just as short counting times are
used with a scaler when the counting rate is high . In some instruments , the time
constant appropriate to each scale is fixed by the manufacturer , and in others the
