Crucial Information

Precision measurements of the Z = 2 component in cosmic radiation provide crucial information about the origin and propagation of the second most abundant cosmic ray species in the Galaxy (9% of the total). These measurements, acquired with the PAMELA space experiment orbiting Earth, allow to study solar modulation in details. Helium modulation is compared to the modulation of protons to study possible dependencies on charge and mass. The time dependence of helium fluxes on a monthly basis measured by PAMELA has been studied for the period between July 2006 to January 2016 in the energy range from 800 MeV/n to ~ 20 GeV/n.

Cosmic Ray Flux

Instruments were flown on the Pioneer 6 and 7 spacecraft during 1965-66 to study the degree of anisotropy of cosmic radiation in the energy range 7.5-90 Mev/nucleón. The instruments record the cosmic ray fluxes from each of four contiguous ‘quadrants’ of azimuthal rotation of the spacecraft, for each of three energy windows 7.5-45 Mev, 45-90 Mev, and 150-350 Mev for alpha particles and heavier nuclei. In addition, the counting rate of all particles of energy >7.5 Mev is recorded, thereby providing cosmic ray data of high statistical precision useful in the study of fast changes in the cosmic ray flux.

Experimental Values

The charged current neutrino–nucleon interaction cross-section is evaluated using Thermodynamical Bag Model (TBM) in the neutrino energy range 1 < Eν < 200 GeV with the value of the four-momentum transfer squared 0.1 < Q2 < 20 GeV 2 and the Bjorken variable 0.1 < x < 0.5. The hadronic current carries the linear moments of the reaction that depend on the Bjorken scaling variable x as well as the four-momentum transfer. The results obtained have been compared with the experimental values.
