From Coulomb excitation cross sections to nonresonant astrophysical rates in three-body systems: The Ne-17 case
Journal article, 2018
Coulomb and nuclear dissociation of Ne-17 on light and heavy targets are studied theoretically. The dipole E1 strength function is determined in a broad energy range including energies of astrophysical interest. Dependence of the strength function on different parameters of the Ne-17 ground-state structure and continuum dynamics is analyzed in a three-body model. The discovered dependence plays an important role for studies of the strength functions for the three-body E1 dissociation and radiative capture. The constraints on the [s(2)]/[d(2)] configuration mixing in Ne-17 and on p-wave interaction in the O-15+p channel are imposed based on experimental data for Ne-17 Coulomb dissociation on heavy target.
