Comparison of electromagnetic and nuclear dissociation of ¹⁷Ne

NUCLEAR REACTIONS H, C, Pb(¹⁷Ne, p¹⁵O), (¹⁷Ne, p¹⁴O), (¹⁷Ne, 2p¹⁵O), (¹⁷Ne, 2p¹⁴O), E=500 MeV/nucleon; measured reaction products, mass spectra of ¹³O, ¹⁴O and ¹⁵O isotopes, (¹⁴O)p-, (¹⁴O)2p-, (¹⁵O)p-, (¹⁵O)2p-coin using lead, carbon, and polyethylene targets and ALADIN-R3B setup at GSI; deduced transverse momentum distributions of ¹⁴O and ¹⁵O, relative energy spectra, inclusive σ, σ(1p) and σ(2p) for fragmentation of ¹⁷Ne in ¹⁴O and ¹⁵o for different targets, electromagnetic dissociation (EMD) cross sections. Electromagnetic and nuclear dissociations. One-proton knockout, and three body ¹⁵O+2p correlations. Comparison of measured cross sections and energy spectra with calculations using three-body ¹⁵O+2p model, and Hartree-Bogoliubov theory. Relevance to ¹⁵O(2p, γ)¹⁷Ne capture reaction in astrophysical rp-process.
