Abstract

Transverse electroexcitation of states in 19F at excitation energies below 4.4 MeV is described. Cross-section measurements were performed with the 500 MeV electron-scattering facility at NIK.-HEF-K at a scattering angle of 154° and in the momentum-transfer range q = 1.4–2.6 fm−1. Some additional low-q data were measured with the 180° electron-scattering facility. The form factors for the negative-parity states are compared with predictions from a 1 ħω shell-model calculation in the full 1p-2sld configuration space. For the positive-parity states a comparison is made with 0 ħω shell-model calculations in the full 2s1d configuration space and with 2 ħω shell-model calculations in a space made up of all shells up to the 1f72 orbit. The large differences observed between the form factors calculated in the 0 ħω and 2 ħω spaces are ascribed to effects of space truncation.

      A comprehensive theoretical and experimental investigation of electron scattering on 19F was presented by Brown et al. [4]. Transverse electroexcitation of states in 19F at excitation energies below 4.4 MeV were described by Donne et al. [5] using electron-scattering facility. The form factors for the positive and negative parity states are compared with predictions from shell-model calculation.
