Study of 45Ar through (d, p) reaction at SPIRAL

The structure of the neutron-rich nucleus 45Ar has been investigated through the d(44Ar,45Ar)p transfer reaction. Radioactive beam of 44Ar at 10 A MeV has been provided by the SPIRAL facility at GANIL. The protons corresponding to a neutron pick-up on bound or unbound states mechanism in 45Ar nuclei were detected at backward angles by the detector array MUST. The transfer-like ejectiles were detected in the SPEG spectrometer. Level scheme, spin assignments and spectroscopic factors have been deduced for 45Ar and compared to shell model predictions. These parameters will be subsequently used to infer (n, γ) cross sections in the Ar isotopic chain for astrophysical purposes.
