摘要：

A new particle, the cosmion, has been proposed to be the dark matter of the Universe and to explain the solar deficit by cooling the solar core to reduce B8 production. Such cosmions in the galactic halo would scatter from nuclei in terrestrial detectors. Measurements were made in Si ionization detectors in a very-low-background environment down to energies of 1.1 keV. These results exclude nearly all of the mass range possible for cosmions with coherent nuclear interactions. © 1990 The American Physical Society.
