Schematic illustration of the quasi-elastic reaction investigated by Duer et al. Top: quasi-elastic scattering of the helium-4 (4He) core from a helium-8 (8He) projectile off a proton target in the laboratory frame. The length of the arrows represents the momentum per nucleon (the velocity) of the incoming and outgoing particles. Zbeam is the beam axis. Bottom: the equivalent p-4He elastic scattering in their center-of-mass frame, where we consider reactions at backward angles close to 180°. In this frame, the momentum of the proton balances that of 4He, Pp=−P4He, that is, the proton is four times faster than 4He. Image credit: Duer et al., doi: 10.1038/s41586-022-04827-6.
