Alpha Decay Of Excited States In C-14

Measurements of the C-14(C-14,C-14[Be-10+alpha]) 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 C-14 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 Be-10 ground state or the first excited states. Angular correlation measurements suggest an assignment of J(pi)=3(-) for the 15.6 MeV state.
