The inelastic electron scattering form factor for the $0^{+}$ first excited state of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ has been calculated with wave functions from the recoil corrected continuum shell model. The use of a realistic interaction and proper boundary conditions lead to excellent agreement with experiment. These results demonstrate that this state can be understood as a superposition of simple 1p-1h excitations in the internal coordinates.
