ANGULAR DISTRIBUTION OF SPONTANEOUS FISSION TRACKS IN ZIRCON UNDER VARIOUS ETCHING CONDITIONS
翟鹏济, 赵云龙 · Chinese Science Bulletin · 1992
Ⅰ. INTRODUCTION When developing the technique of fission track dating, people found that the etching rates vary markedly with the crystallographic orientation of the etched surfaces so that the shapes of tracks are different, and that even on the same Crystalline surface the etching is
