The behavior of the specific heat of liquid He3, over a wide range of temperature, indicates a wiggle in the single-(quasi) particle spectrum e (k) at kF. This wiggle corresponds to the enhancement of the effective mass m*(k) at kF of current interest in nuclear physics. It can be quantitatively understood from the microscopic Hamiltonian within correlated-basis perturbation theory.
