Abstract
The nuclear structure of 14N is studied in the framework of the hole-hole Tamm-Dancoff Approximation (hhTDA) and hole-hole Random Phase Approximation (hh RPA). The Hamiltonian is diagonalized within a model space with particle orbits {1d5/2, 1d3/2, 2s1/2 and 1f7/2}and the hole orbits {1s1/2, 1p3/2 and 1p1/2} using Warburton and Brown interaction WBP. The TDA and RPA amplitudes are used to calculate the longitudinal and transverse electron scattering form factors. The results for JfπTfExMeV= 1+0(0.0), 0+1(2.313), 1+(3.945), 2−0(5.106) and 3−0(5.834) states are interpreted in terms of the harmonic-oscillator (HO) wave functions of size parameter b and compared with the available experimental data. Configurations outside the model space are included approximately, in terms of polarization effective charges and g-factors.
