Gaussian Function


The Gaussian function is a mathematical function, characterized by a bell-shaped peak ("bell curve"), without the wide tail of a Lorentzian function. A typical Gaussian peak is illustrated in the graph below:-

In powder diffraction we usually plot the diffracted intensity, I, along the y-axis, and the intensity distribution is given by:-
