Search for anomalously heavy isotopes of helium in the Earth's atmosphere

Abstract
Motivated by the theoretical hypotheses on the existence of heretofore unobserved stable elementary particles and exotic nuclear states, we searched for doubly-charged particles, as anomalously heavy isotopes of helium, in the Earth's atmoshpere using a sensitive laser spectroscopy technique. The concentration of noble-gas-like atoms in the atmosphere and the subsequent very large depletion of the light He-3,4 isotopes allow us to set stringent limits on th abundance: 10^-13 to 10^-17 per atom in the solar system, over the mass range of 20 to 10,000 amu.
