Implication

Experimental study demonstrates background-suppressed simultaneous proton reaction measurements in xenon-124 ions, highlighting improved constraints for stellar nucleosynthesis models.

Key Points

To measure proton-induced reaction cross sections near astrophysical energies in an ion storage ring using a background suppression method.
Circulated and decelerated xenon-124 ions to astrophysical energies near the neutron threshold energy within a storage ring.
Applied a background suppression technique designed to eliminate Rutherford elastic scattering events.
Simultaneously measured the 124Xe(p,γ) and 124Xe(p,n) reaction channels.
Suppressed experimental background by approximately 1 order of magnitude.
Achieved the first measurement of a (p, n) reaction cross section inside an ion storage ring.
Supplied empirical constraints for Hauser-Feshbach theory and enabled cross section extrapolations toward the astrophysical Gamow window.
