The source-sample-detector efficiency for the recessed source geometry was evaluated, using Monte Carlo techniques, for a variety of samples and sources and found to be superior to that for other geometries in energy-dispersive X-ray fluorescence analysis. The samples considered were those with atomic number in the range 14 - 44 and the radioactive sources were 55Fe, 244Cm and 109Cd. Efficiencies well above 1% can be achieved for the recessed source geometry and samples with atomic number above 20. The values attainable are around four times larger than those for the annular source geometry.
