Ion probe analysis of artificially implanted ions in terrestrial samples and surface enhanced ions in lunar sample 76215,77

Zinner, E.; Walker, R. M.; Chaumont, J.; Dran, J. C. (Pergamon Press, 1976)

We used the ARL ion probe at the JSC to measure concentration depth profiles of artificially implanted ions in terrestrial minerals and of natural elements on the surface of a recently exposed lunar plagioclase crystal.
Ion probe surface concentration measurements of Mg and Fe and microcraters in crystals from lunar rock and soil samples

Zinner, E.; Walker, R. M.; Chaumont, J.; Dran, J. C. (Pergamon Press, 1977)

Measurements of solar wind implanted ions and microcraters on the surface of lunar rock crystals and soil grains allow the study of solar activity and the interplanetary environment and their possible changes in the past. ...
Surface concentrations of Mg, Ti, Fe and surface features in individual plagioclase crystals from lunar soil samples

Zinner, E.; Dust, S.; Chaumont, J.; Dran, J. C. (Pergamon Press, 1978)

Surface enhancements of Mg, Ti and Fe were measured with an ARL-IMMA and a CAMECA IMS-300 ion microprobe in 100-200 mesh plagioclase grains from eight different lunar soils. Enhancements of Mg, Ti and Fe were found in ...
