Abstract

The production of intense beams of light radioactive nuclei can be achieved at the SPIRAL2 facility using intense stable beams accelerated by the driver accelerator and impinging on light targets. The isotope ¹⁴O is identified to be of high interest for future experiments. The excitation function of the production reaction ¹²C(³He, n)¹⁴O was measured between 7 and 35MeV. Results are compared with literature data. As an additional result, we report the first cross-section measurement for the ¹²C(³He, + n)¹⁰C reaction. Based on this new result, the potential in-target ¹⁴O yield at SPIRAL2 was estimated: 2.4×10¹¹ pps, for 1mA of ³He at 35MeV. This is a factor 140 higher than the in-target yield at SPIRAL1.
