Pauli blocking can be activated and customized using the Pauli_Blocking section within Collision_Term. For example:

Collision_Term:
    Pauli_Blocking:
        Spatial_Averaging_Radius: 1.86
        Gaussian_Cutoff: 2.2
        Momentum_Averaging_Radius: 0.08

Gaussian_Cutoff — double, optional, default = 2.2

Radius in fm at which Gaussians used for smoothing are cut.

Momentum_Averaging_Radius — double, optional, default = 0.08

Radius in GeV of sphere for averaging in the momentum space.

Spatial_Averaging_Radius — double, optional, default = 1.86

Radius in fm of sphere for averaging in the coordinate space.
