An investigation of the 144Sm(α, 3He)145Sm reaction

The 144Sm(α, 3He)145Sm stripping reaction has been studied up to 3 MeV excitation energy with a 40 MeV α-beam. Angular distributions have been recorded, and spectroscopic factors are deduced using a standard DWBA procedure. The reaction favours high-l transfers, and is found to be very useful for the investigation of large-j states. From a comparison with the spectroscopic factors known from the 144Sm(d, p)145Sm reaction the normalization factor for the (α, 3He) reaction is found to depend strongly on the optical model parameters and on the transferred angular momentum l.
