| For our experiments, we
use the complementary techniques of x-ray and neutron
scattering. Using beams of these two particles, we can probe the
internal structure and dynamics of many materials on the atomic
scale. |

| To learn more about scattering, the
following books are good for beginners: |

|
| The majority of our experimental work
consists of reflectivity and diffuse scattering studies of
materials. Here are some good reference books |
