| Title | Measuring the cross section of the 15N(a,¿)19F reaction1 using a single-fluid bubble chambe | ||||
| Abstract | 15N(?,?)19F is believed to be the primary means of stellar nucleosynthesis of fluorine. Here we present the use of a single-fluid bubble chamber to measure the cross section of the time-inverse photo-dissociation reaction. The method benefits from a luminosity increase of several orders of magnitude due to the use of a thicker liquid target ? as compared to thin films or gas targets - and from the reciprocity theorem. We discuss the results of experiments at the Thomas Jefferson National Accelerator Facility, where the cross section of the photodisintegration process 19F(?, ?)15N was measured by bombarding a superheated fluid of C3F8 with bremsstrahlung ?-rays produced by impinging an electron beam on a Cu radiator. A photodissociation yield was measured and the cross section was extracted by performing a convolution with a Monte Carlo-generated ?-ray beam spectrum. The measurement produced a cross section that was then time inverted using the reciprocity theorem. The cross section | ||||
