description:
	The purpose of the experiment is to measure dispersion of valence electron states
	in insulating copper-oxides using x-ray raman scattering at the CuK resonance.
	We will use the Si(333) beam at 9 keV (100 meV bandwidth) and a Ge(733)
	high resolution analyzer as optics.  The crystals are insulating Sr2CuO2Cl2 and
	La2CuO4.  We hope to measure the charge transfer gap (1.8 eV) dispersion for
	comparison to EELS measurements made in 1996.

equipment+required:
	high resolution translation stage (10 micron), huber tilt stage with gear boxes, 

experiment:
	X-ray Raman Scattering from Insulating Cuprates

hazards:
	There are no special hazards associated with this experiment.
