DESCRIPTION:Speakers: Jiahui Wei (Université de Genève)\nPrecise knowled
 ge of the spectra of secondary cosmic-ray isotopes provides a powerful too
 l to constrain cosmic-ray propagation models. In particular\, $^3$He isoto
 pes in cosmic rays are produced by interactions of primary $^4$He with the
  interstellar medium\; similarly\, lithium and beryllium are mainly produc
 ed by the fragmentation of heavier primary cosmic-ray nuclei. Among light 
 isotopes\, the radioactive $^{10}$Be\, which has half-life comparable to t
 he cosmic-ray residence time in the Galaxy\, provides crucial complementar
 y information. We present precision measurements of the fluxes of helium i
 sotopes\, $^3$He and $^4$He\, lithium isotopes\, $^6$Li and $^7$Li\, and b
 eryllium isotopes\, $^7$Be\, $^9$Be and $^{10}$Be\, as well as the time de
 pendence of the $^3$He/$^4$He flux ratio\, based on data collected by AMS 
 on the International Space Station.\n\nhttps://indico.ific.uv.es/event/617
