Abstract

The 12C(13C,α)21Ne reaction has been measured with a 13C beam energy of 20 MeV. States in 21Ne have been populated between 0 and 12 MeV with a resolution of ~350 keV (FWHM). A coincidence experiment has been performed in which either the bound 21Ne nucleus or the 20Ne nucleus produced via neutron decay is detected. This permitted the 21Ne states undergoing gamma decay and neutron decay to the ground and first excited states in 20Ne to be determined. The current measurements suggest several errors in the current compilation for 21Ne.
