Description of isospin mixing by a generator coordinate method

NUCLEAR STRUCTURE ¹⁴C, ¹⁴N; calculated energy curves as functions of quadrupole deformation parameter β. ¹⁴N; calculated levels, J, π, isospin T=1 components. ¹⁴N; calculated B(M1), B(E1), B(E2), magnetic dipole moments, electric quadrupole moments, spectroscopic factors, and overlap functions for low-lying, low-spin positive- and negative-parity states. Generator coordinate method (GCM) by applying the Fermi transition operator to the wave functions of isobars, for describing isospin mixing. Comparison with experimental data.
