The partial widths are determined for stop decays to top quarks and gl
uinos, and gluino decays to stop particles and top quarks (depending o
n the masses of the particles involved). The widths are calculated inc
luding one-loop SUSY-QCD corrections. The radiative corrections for th
ese strong-interaction decays are compared with the SUSY-QCD correctio
ns for electroweak stop decays to quarks and neutralinos/charginos and
top-quark decays to stops and neutralinos.
