Two spin \(\frac{1}{2}\) fermions of mass m are confined to move in a one-dimensional infinite potential well of width L. If the particles are known to be in a spin triplet state, the ground state energy of the system (in units of \(\frac{{{{\rm{h}}^{\rm{2}}}{{\rm{\pi }}^{\rm{2}}}}}{{{\rm{2m}}{{\rm{L}}^{\rm{2}}}}}\)) is
