  The measurement of muon momentum by Multiple Coulomb Scattering is a crucial
ingredient to the reconstruction of {\nu}{\mu} CC events in the ICARUS-T600
liquid argon TPC in absence of magnetic field, as in the search for sterile
neutrinos at Fermilab where ICARUS will be exposed to ~1 GeV Booster neutrino
beam. A sample of ~1000 stopping muons produced by charged current interactions
of CNGS {\nu}{\mu} in the surrounding rock at the INFN Gran Sasso underground
Laboratory provides an ideal benchmark in the few-GeV range since their
momentum can be directly and independently obtained by the calorimetric
measurement. Stopping muon momentum in the 0.5- 4.5 GeV/c range has been
reconstructed via Multiple Coulomb Scattering with resolution ranging from 10
to 25 % depending on muon energy, track length and uniformity of the electric
field in the drift volume.
