abstract = {Precision measurements by the Alpha Magnetic Spectrometer
(AMS) on the International Space Station of 3He and 4He
fluxes are presented. The measurements are based on 100
million 4He nuclei in the rigidity range from 2.1 to 21 GV
and 18 million 3He from 1.9 to 15 GV collected from May 2011
to November 2017. We observed that the 3He and 4He fluxes
exhibit nearly identical variations with time. The relative
magnitude of the variations decreases with increasing
rigidity. The rigidity dependence of the 3He/4He flux ratio
is measured for the first time. Below 4 GV, the 3He/4He flux
ratio was found to have a significant long-term time
dependence. Above 4 GV, the 3He/4He flux ratio was found to
be time independent, and its rigidity dependence is well
described by a single power law ∝RΔ with
Δ=−0.294±0.004. Unexpectedly, this value is in agreement
with the B/O and B/C spectral indices at high energies.},
