We are exploiting the results of the exact solution for the ground state of the one-dimensional spinless quantum gas of Fermions with mu/x(ij)(2) particle-particle interaction, and analyze particle-number fluctuations for mu = -1/4, 0, and 2. These are suppressed by repulsive interaction (mu > 0), enhanced by attraction (mu < 0), and may therefore measure the kind and strength of correlation. Other recently proposed purely quantum-kinematical measures of the correlation strength arise from the small-separation behavior of the pair density or from the non-idempotency of the momentum distribution and its large-momenta behavior.
