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

The structure of the neutron-rich nucleus Ar-45 has been investigated through the d(Ar-44, Ar-45)p transfer reaction. Radioactive beam of (44)AT 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 Ar-45 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 Ar-45 and compared to shell model predictions. These parameters will be subsequently used to infer (n, gamma) cross sections. in the At isotopic chain for astrophysical purposes.
