Description
17Ne is a proton-dripline nucleus that has raised interest in nuclearstructure
physics in recent years. As a (15O+2p) Borromean 3-body
system, it is often considered to be a 2-proton-halo nucleus, yet lacking
concluding experimental quantification of its structure. We have
studied breakup reactions of 500 AMeV 17Ne secondary beams in inverse
kinematics using the R3B-LAND setup at GSI. The foci were
on (p,2p) quasi-free scattering on a CH2 target, and on one-protonknockout
reactions on a carbon target. Recoil protons have been detected
with Si-Strip detectors and a surrounding 4pi NaI spectrometer.
Furthermore, projectile-like forward protons after one-proton knockout
from 17Ne have been measured in coincidence with the 15O residual
core. The resulting relative-energy spectrum of the unbound 16F, as
well as proton-removal cross sections with CH2 and C targets, and the
transverse-momentum distributions of the residual fragments will be
presented. Conclusions on the ground-state structure of 17Ne will be
discussed.
