Transfer to the Continuum of ~(14)C via (~(18)O, ~(16)O) Reaction~1

摘要

A study of the continuum of ~(14)C populated by the ~(12)C(~(18)O, ~(16)O)~(14)C reaction at 84 MeV incident energy has been performed. The ejectiles have been momentum analyzed at forward angles by the MAGNEX magnetic spectrometer. The energy spectra were obtained up to about 20 MeV excitation energy. The scattering of two neutrons independently removed from the projectile as it passes the target nucleus has been described by means of an optical potential with a semi-classical approximation for the relative motion. The calculations describe a significant part of the continuum observed in the energy spectra. In particular, a resonance of the residual nucleus dominates the region near the two-neutron emission threshold.
