Discussion on the Graphite Yield of Zn-TiH2 Method in the Preparation of Accelerator Mass Spectrometry 14C Sample

Discussion on the Graphite Yield of Zn-TiH2 Method in the Preparation of Accelerator Mass Spectrometry 14C Sample

There are many kinds of methods for preparing graphite target for 14C dating by accelerator mass spectrometer (AMS). Increasing the yield of graphite is of great significance for optimizing the preparation processes of graphite target and improving the performance of graphite target. In this paper,...
