dc.description.abstractEnThe proton drip-line nucleus <sup loc="post">17</sup>Ne is considered a good candidate for a Borromean two-proton halo with a <sup loc="post">15</sup>O + p + p structure. Angular distributions of the elastic scattering and inclusive <sup loc="post">15</sup>O production for a 136 MeV <sup loc="post">17</sup>Ne beam incident on a <sup loc="post">208</sup>Pb target were measured for the first time at the SPIRAL1 facility, GANIL. Use of the GLORIA detector array allowed high-resolution data over a wide angular range from <math altimg="si1.svg"><msup><mrow><mn>20</mn></mrow><mrow><mo>∘</mo></mrow></msup></math> up to <math altimg="si11.svg"><msup><mrow><mn>95</mn></mrow><mrow><mo>∘</mo></mrow></msup></math> in the laboratory frame to be obtained. The elastic scattering angular distribution shows similarities with those for both <sup loc="post">6</sup>He and <sup loc="post">20</sup>Ne at equivalent collision energies with respect to the corresponding Coulomb barriers, exhibiting the suppression of the Coulomb rainbow peak characteristic of strong coupling. Optical model and coupled channel fits suggest that this is due to a combination of coupling to low-lying quadrupole resonances and Coulomb dipole coupling to the low-lying continuum, although their relative importance depends on the relevant <math altimg="si3.svg"><mi>B</mi><mo stretchy="false">(</mo><mi>E</mi><mn>2</mn><mo stretchy="false">)</mo></math> values which remain to be firmly determined.
