Thermodynamic measurements reveal that the Pauli spin susceptibility in a strongly correlated low-disordered two-dimensional electron system in silicon becomes enhanced by almost an order of magnitude at low electron densities and has a critical behavior close to the metal-insulator transition point. This provides thermodynamic evidence for the existence of a phase transition.
