      abstract     = {In our Galaxy, light antinuclei composed of antiprotons and
                      antineutrons can be produced through high-energy cosmic-ray
                      collisions with the interstellar medium or could also
                      originate from the annihilation of dark-matter particles
                      that have not yet been discovered. On Earth, the only way to
                      produce and study antinuclei with high precision is to
                      create them at high-energy particle accelerators. Although
                      the properties of elementary antiparticles have been studied
                      in detail, the knowledge of the interaction of light
                      antinuclei with matter is limited. We determine the
                      disappearance probability of $^{3}\overline{\rm He}$ when it
                      encounters matter particles and annihilates or disintegrates
                      within the ALICE detector at the Large Hadron Collider. We
                      extract the inelastic interaction cross section, which is
                      then used as input to calculations of the transparency of
                      our Galaxy to the propagation of $^{3}\overline{\rm He}$
                      stemming from dark-matter annihilation and cosmic-ray
                      interactions within the interstellar medium. For a specific
                      dark-matter profile, we estimate a transparency of about
                      50\%, whereas it varies with increasing $^{3}\overline{\rm
                      He}$ momentum from 25\% to 90\% for cosmic-ray sources. The
                      results indicate that $^{3}\overline{\rm He}$ nuclei can
                      travel long distances in the Galaxy, and can be used to
                      study cosmic-ray interactions and dark-matter annihilation.},
