Abstract

The JENSA gas-jet target was designed for experiments with radioactive beams provided by the rare isotope re-accelerator ReA3 at the National Superconducting Cyclotron Laboratory. The gas jet will be the main target for the Separator for Capture Reactions SECAR at the Facility for Rare Isotope Beams on the campus of Michigan State University, USA. We describe the advantages of a gas-jet target, detail the current recirculating gas system, and report recent measurements of helium jet thicknesses of up to about 10¹⁹ atoms/cm². A comparison with other supersonic gas-jet targets is presented.

A gas jet target for radioactive ion beam experiments

Journal Article Chipps, K. A. ; Greife, U. ; Hager, U. ; ... - AIP Conference Proceedings

New radioactive ion beam (RIB) facilities, like FRIB in the US or FAIR in Europe, will push further away from stability and enable the next generation of nuclear physics experiments. Thus, the need for improved RIB targets is more crucial than ever: developments in exotic beams should coincide with developments in targets for use with those beams, in order for nuclear physics to remain on the cutting edge. Of great importance to the future of RIB physics are scattering, transfer and capture reaction measurements of rare, exotic, and unstable nuclei on light targets such as hydrogen and helium.

The first science result with the JENSA gas-jet target: Confirmation and study of a strong subthreshold ${}^{18}F (p, α) {}^{15}O$ resonance

Journal Article Bardayan, D. W. ; Chipps, K. A. ; Ahn, S. ; ... - Physics Letters B

The astrophysical ¹⁸F(p,α)¹⁵O rate determines, in large part, the extent to which the observable radioisotope ¹⁸F is produced in novae. This rate, however, has been extremely uncertain owing to the unknown properties of a strong subthreshold resonance and its possible interference with higher-lying resonances. In addition, the new Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas-jet target has been used for the first time to determine the spin of this important resonance and significantly reduce uncertainties in the ¹⁸F(p,α)¹⁵O rate.

Dissipative Reactions with Intermediate-Energy Beams: A Novel Approach to Populate Complex-Structure States in Rare Isotopes

Journal Article Gade, A. ; Brown, B. A. ; Weisshaar, D. ; ... - Physical Review Letters

A novel pathway for the formation of multiparticle-multihole excited states in rare isotopes is reported from highly energy- and momentum-dissipative inelastic-scattering events measured in reactions of an intermediate-energy beam of ³⁸Ca on a Be target. The negative-parity, complex-structure final states in ³⁸Ca are observed following the in-beam γ-ray spectroscopy of events in the ⁹Be(³⁸Ca, ³⁸Ca + γ)X reaction in which the scattered projectile loses longitudinal momentum of order Δp_|| = 700 MeV/c. Here, the characteristics of the observed final states are discussed and found to be consistent with the formation of excited states involving the rearrangement of multiple nucleons inmore »« less

Proton capture on ³⁴S in the astrophysical energy regime of O-Ne novae

Journal Article Lovely, M. ; Lennarz, A. ; Connolly, D. ; ... - Physical Review C

Nuclear reaction sensitivity studies have shown that the final isotopic abundance of O-Ne nova nucleosynthesis is dependent on the ³⁴S(p,γ)³⁵Cl reaction at astrophysical energies corresponding to peak nova burning temperatures of 0.1–0.4 GK. Isotopic ratios of the S, Cl, and Ar products are all used in various methods of cosmochemical analysis of presolar meteoritic grains. Due to the lack of direct experimental data, the ³⁴S+p reaction rate has been estimated using statistical modeling or information from indirect nucleon transfer experiments. In order to provide direct reaction information, here the resonance strengths of several low energy resonances, E_c.m. = 272–495 keV,more »« less
