  The collision frequency (also known as the inverse scattering lifetime) can
be self-consistently calculated from the imaginary part of the zero-temperature
elastic scattering cross-section in unconventional superconductors. We find
these types of studies helpful to describe a hidden self-consistent damping due
to incoherent fermions in two physical spaces: The Phase Space of the
Nonequilibrium Statistical Mechanics, and the Configuration Space of
Nonrelativistic Quantum Mechanics. The direct relation of the collision
frequency with those well-known Physical Spaces is addressed in a singular way
this time. Since the use of collisions for different elastic scattering
regimes, is a well-developed formalism using retarded, and advanced Green
functions in Many Body Physics; in order to describe our findings, we define
and characterize a Reduced Phase Space for collision frequencies in the triplet
strontium ruthenate compound and the singlet doped with strontium lanthanum
cuprate ceramic. Both compounds display different nodal behavior of the
superconducting order parameter. In this work, their zero gap behavior is
numerically scanned and used to give some illustrative examples. Finally, it
intuitively explores the geometrical nonlocality of the collision frequency of
this type of hidden self-consistency in the Boltzmann equation, when the zero
superconducting gap value drives the physics below the transition temperature,
and incoherent fermions quasiparticles govern several nonequilibrium phenomena
since the macroscopic behavior remarkably changes with the strontium atomic
potential strength, and the concentration inherent to both compounds.
