α decay of excited states in C 14

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