Problem 1 - getting used to q

For the data presented in class for the siloxane-urethaneureas, over what theta and two theta ranges are the data shown?

What is the theta for the highest datum for each of the five data sets?

Also give the corresponding 'interaction distances' (d) for each theta you calculated.

Problem 2 - what can we measure?

In a manner similar to what we did in class, albeit much more briefly, locate three papers or reports of studies that deal with saxs measurements. Do not use those given in class or anything intimately connected with your own saxs measurements. Each paper should discuss the measurement by saxs of different types of quantities; e.g., they should not all be about the measurement of precipitate particle sizes in heat treated alloys. My recommendations are to google 'saxs' or SciFinder 'saxs' or 'small angle x-ray scattering'.

Describe in roughly three sentences, and maybe a drawing, what was measured.
