Two-Neutron Stripping in (18O,16O) and (t,p) Reactions.

The ¹²C(¹⁸O,¹⁶O)¹⁴C reactions has been investigated at 84 MeV incident energy. The charged ejectiles produced in the reaction have been momentum analyzed and identified by the MAGNEX magnetic spectrometer. Q-value spectra have been extracted with an energy resolution of 160 keV (Full Width at Half Maximum) and several known bound and resonant states of ¹⁴C have been identified up to 15 MeV. In particular, excited states with dominant 2p - 4h configuration are the most populated. The absolute values of the cross sections have been extracted showing a striking similarity with those measured for the same transitions by (t,p) reactions. This indicates that the effect of the ¹⁶O core is negligible in the reaction mechanism. [ABSTRACT FROM AUTHOR]
