|---|
| [5ed76f8] | 12 | This tool estimates real space dimensions from the position or spacing of |
|---|
| 13 | features in recipricol space. In particular a particle of size $d$ will |
|---|
| 14 | give rise to Bragg peaks with spacing $\Delta q$ according to the relation |
|---|
| 15 | |
|---|
| 16 | .. math:: |
|---|
| 17 | |
|---|
| 18 | d = 2\pi / \Delta q |
|---|
| 19 | |
|---|
| 20 | Similarly, the spacing between the peaks in Kiessig fringes in reflectometry |
|---|
| 21 | data arise from layers of thickness $d$. |

| 26 | -------------- |
|---|
| [ec392464] | 27 | |
|---|
| [5ed76f8] | 28 | To get a rough thickness or particle size, simply type the fringe or peak |
|---|
| [1e01486] | 29 | position (in units of 1/|Ang|\) and click on the *Compute* button. |
