Optimal Experimental Conditions for Charge Density DeterminationThis chapter deals with the specific and well defined task: determining structure factor amplitudes from measurements of Bragg reflections on single crystals using X-ray or neutron radiation. It may however be worthwhile first to discuss in more general terms the optimal conditions for measuring any piece of information.

Entropy reduction in mathematical giftednessas been used to investigate the behaviour of the integrated reflectivity R with temperature. The reflections (200) and (600) have been measured, with a symmetric Laue geometry. The results are given in table 1. The results are reversible as a function of temperature variation.

lute reliability of our data. In general we will assign an error to each observation and use this error in the mathematical analysis. For an observed squared structure amplitude F. we estimate an error σ (F.).
