I had been trying to get the people at Los Alamos and Sandia to recognize that there was a serious problem with zeolite stability if heat generating wastes were emplaced below the water table at Yucca Mountain. They thaught I was being disloyal and stopped sending me to meetings. So I wrote this paper and submitted it and sent it through for internal review at the same time. The next day I was looking for another job. What does this tell you about scientific intergrety at the National Labs?

1969

J. R. Smyth (1969) Orthopyroxene - high - low clinopyroxene inversions. Earth and Planetary Science Letters 5, 406-407. This is the first experimental observation of the displacive P2₁/c to C2/c transformation in pyroxene and of the reconstructive Pbca to C2/c transformation as well. I designed and built the heater system and the evacuation and encapsulation system for the experiment.

J. R. Smyth and J. V. Smith (1969) Electrostatic energy for ion clustering in intermediate plagioclase feldspars. Mineralogical Magazine 37, 181-184. This was my first attempt to calculate Madelung potentials and use them for mineralogical applications.

American Mineralogist 53, 1941-1845. reprint This is Opus 1, my first paper. I did this study with Paul Moore. We measured intensities from Weissenberg films by visual estimation! How's that for a bit of history?
