Study of neutron-rich argon isotopes in β-decay

Abstract The study [Nucl. Phys. A 722 (2003) 424c] of the neutron rich nuclei near the N=28 magic number was performed at GANIL-France. This letter reports on preliminary results concerning isotopes 44,45,46 Ar. Schemes of excited levels were deduced from the γ– γcoincidences. Levels above S n energy were suggested from the γ- n coincidences for 46 Ar.
