II. Nuclear Physics Experiment
We have a on-site facility of 3MV 9SDH-2 pelletron tandem accelerator which was
installed in 1989. Since then the accelerator became an important facility for
experimental research in the low energy nuclear physics, accelerator based atomic
physics, and applied accelerator technology. The accelerator system has two negative
