DESCRIPTION
Calculates the interparticle structure factor, S(q), for monodisperse spherical particles interacting through hard sphere (excluded volume) interations. The solution uses the Percus-Yevick closure.
VARIABLES
Input Variables (default values):
Parameter | Variable | Value |
---|---|---|
0 | Radius (Å) | 50.0 |
1 | Volume Fraction (0-1) | 0.2 |
USAGE NOTES
The returned value is dimensionless.
The interaction potential is:
where r is the radial distance from the center of the sphere of radius R.

TEST DATASET
This example dataset is produced by calculating the HardSphere using 128 data points, qmin = 0.001 Å-1, qmax = 0.3 (Å-1) and the above default parameter values.
