$\alpha$ decay of excited states in $^{14}$C
Résumé
Measurements of the $^{14}$C($^{14}$C,$^{14}$C[$^{10}$Be + α]) breakup reaction have been made at a beam energy of 98.2 MeV. The studies were performed with two charged-particle telescopes that permitted the energy, mass, charge, and emission angle of each detected particle to be determined. A series of $^{14}$C excited states at energies of 14.3, 14.8 15.6, 16.4, 17.3, 18.6, 19.8, 20.6, and 21.6 MeV was observed to decay to either the $^{10}$Be ground state or the first excited states. Angular correlation measurements suggest an assignment of J$^{PI}$ = 3$^{−}$ for the 15.6 MeV state.
