  We take a new look at $^{6}\textrm{He}$ halo nucleus and set up a halo
effective field theory at low energies to calculate the charge form factor of
${}^{6}\textrm{He}$ system with resonant P-wave interaction. P-wave Lagrangian
has been introduced and the charge form factor of ${}^{6}\textrm{He}$ halo
nucleus has been obtained at Leading-Order. In this study, the mean-square
charge radius of ${}^{6}\textrm{He}$ nucleus relative to ${}^{4}\textrm{He}$
core and the root-mean-square (r.m.s) charge radius of ${}^{6}\textrm{He}$
nucleus have been estimated as $\langle r_{E}^{2}\rangle=1.408\;
\textrm{fm}^{2}$ and $\langle r_{E}^{2}\rangle_{{}^{6}He}^{\frac{1}{2}}=2.058
\;\textrm{fm}$, respectively. We have compared our results with the other
available theoretical and experimental data.
