180°electron scattering from C14

Inelastic electron scattering cross sections for C14 have been measured at a scattering angle of 180°, with incident beam energies ranging from 81.9 to 268.9 MeV. Transverse form factors were measured for transitions to low-lying natural-parity states, to unnatural-parity stretchedJ=4- states, and to the J=2- analog to the B14 ground state. Cross sections for 4- states at 11.7 and 17.3 MeV are combined with pion scattering data to determine the isoscalar and isovector transition amplitudes. Form factors for other states are compared to shell-model calculations. From the excitation energy of the newly discovered JT=2-2 state at 22.1 MeV, the -1414B Coulomb energy difference is determined to be 2.25±0.10 MeV.
