HIRFL HIRFL Research Research ProgramsPrograms

• Nuclear Physics– Nuclear spectroscopy (SHE, dripline nuclei, exotic decay p

roperties, …)– RIB physics (matter & charge distribution radii, new phen

omena in weakly bound nuclei, …)– Reaction dynamics and nuclear matter (NN cross section,

EoS of the asymmetric nuclear matter, properties of the high baryon density nuclear matter, … )

– Hadron Physics (Hadron spectroscopy, isospin violation process, spin physics, …) --- planned

• Atomic Physics

• Material Science

• Radio-biology & cancer therapy with heavy ions

Exp. Sites at HIRFLExp. Sites at HIRFL ① Low energy site in general ② Atomic physics exp. site ③ SHANSSHANS - Spectrometer for Heavy Atom and Nuclear Structure
