Abstract: We consider optimally spin-squeezed states that maximize the sensitivity of the Ramsey spectroscopy, and for which the signal-to-noise ratio scales as the number of particles N. Using the variational principle we prove that these states are eigensolutions of the Hamiltonian $H(\ensuremath{\lambda})=\ensuremath{\lambda}{S}_{z}^{2}\ensuremath{-}{S}_{x},$ and that, for large N, the states become equivalent to the quadrature squeezed states of the harmonic oscillator. We present numerical results that illustrate the validity of the equivalence.
