Exposure of Nuclear Track Emulsion to He-8 Nuclei at the ACCULINNA Separator

Abstract

Nuclear track emulsion is exposed to a beam of radioactive ${}^8$He nuclei with an energy of 60 MeV and enrichment of about 80% at the ACCULINNA separator. Measurements of 278 decays of the ${}^8$He nuclei stopped in the emulsion allow the potential of the $\hat{I}\pm$ spectrometry to be estimated and the thermal drift of ${}^8$He atoms in matter to be observed for the first time.
