We report the properties of precision time structures cosmic nuclei He, Li, Be, B, C, N, and O fluxes over an 11-year solar cycle from May 2011 to November 2022 in rigidity range 1.92 60.3 GV. The show similar but not identical variations with amplitudes decreasing increasing rigidity. In particular, below 3.64 GV B fluxes, 2.15 are significantly less affected by modulation than He flux. observe that these differences linearly correlated spectral indices fluxes. This shows, a...
We report the properties of primary cosmic-ray sulfur (S) in rigidity range 2.15 GV to 3.0 TV based on 0.38×10^{6} nuclei collected by Alpha Magnetic Spectrometer experiment (AMS). observed that above 90 dependence S flux is identical Ne-Mg-Si fluxes, which different from He-C-O-Fe fluxes. found that, similar N, Na, and Al cosmic rays, over entire range, traditional rays S, Ne, Mg, C all have sizeable secondary components, Mg fluxes are well described weighted sum silicon fluorine flux,...
We present the precision measurements of 11 years daily cosmic positron fluxes in rigidity range from 1.00 to 41.9 GV based on 3.4×10^{6} positrons collected with Alpha Magnetic Spectrometer (AMS) aboard International Space Station. The show distinctly different time variations electron at short and long timescales. A hysteresis between is observed a significance greater than 5σ rigidities below 8.5 GV. On contrary, proton similar variation. Remarkably, we found that are modulated more for 7...
Isotopic composition measurements of singly charged cosmic rays (CR) provide essential insights into CR transport in the Galaxy. The Alpha Magnetic Spectrometer (AMS-02) can identify isotopes up to about 10 GeV/n. However, their identification presents challenges due small abundance deuterons compared proton background. In particular, a high accuracy for velocity measured by ring-imaging Cherenkov detector (RICH) is needed achieve good isotopic mass separation over wide range energies....
Electron capture (EC) decay relies on attachment and stripping cross-sections, that in turn, depend the atomic number of nucleus. We revisit impact EC context high-precision cosmic-ray fluxes measured by AMS-02 experiment. derive solution steady-state a 1D thin disk model including decay. compare our results with relevant elemental isotopic evaluate this process, given precision recent AMS-02, ACE-CRIS, SuperTIGER, Voyager data. find to be at level or larger than recently collected data for...
