Isospin Transport in ⁸⁴ Kr + ^{112 , 124} Sn Collisions at Fermi Energies with the FAZIA Detector

摘要

Isotopically resolved fragments up to Z ≈ 20 have been studied in a test experiment by the FAZIA Collaboration with a three-stage telescope. The reactions ⁸⁴ Kr+ ¹¹² Sn ( n -poor) and ⁸⁴ Kr+ ¹²⁴ Sn ( n -rich) at 35 MeVucleon were measured. The telescope was located near the grazing angle, so the detected fragments are mainly emitted from the phase-space region of the projectile. In the following, evidences for isospin diffusion and drift will be discussed.
