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 $^3$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 $^3$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 $^3$He momentum from 25\% to 90\% for
cosmic-ray sources. The results indicate that nuclei can
travel long distances in the Galaxy, and can be used to
study cosmic-ray interactions and dark-matter annihilation.},
