COSMIC-RAY ABUNDANCES OF THE EVEN CHARGE ELEMENTS FROM soSn TO ssCe MEASURED ON HEA0-3
ثبت نشده
چکیده
OG 1-21 Elements with even atomic number (Z) in the interval 50 ~ Z ~ 58 have beell resolved in the cosmic radiation using the Heavy Nuclei Experiment on the HEA0-3 satirllite. The observation that 50Sn and 56Ba are more abundant that 52 Tc and 54Xe indicates a substantial s-process contribution to the cosmic PV source. A significant abundance of 58Ce provides further support for this finding.

Analysis of a -new, higher resolution data set from the Heavy Nuclei Experiment on the HEA0-3 spacecraft has yielded the cosmic ray abundances relative to iron of oddeven element pairs with atomic number, Z, in the range 33sZs60. The abundances are consistent 'Yith a solar-system source provided an allowance is made for a source fraetionation based on first ionization potential (FIP). However, ...
متن کاملGALACTIC COSMIC RAY ORIGINS AND OB ASSOCIATIONS: EVIDENCE FROM SuperTIGER OBSERVATIONS OF ELEMENTS 26Fe THROUGH 40Zr
We report abundances of elements from 26Fe to 40Zr in the cosmic radiation measured by the SuperTIGER (TransIron Galactic Element Recorder) instrument during 55 days of exposure on a long-duration balloon flight over Antarctica. These observations resolve elemental abundances in this charge range with single-element resolution and good statistics. These results support a model of cosmic ray ori...

The abundances of cosmic-ray helium isotopes between 0.2 and 3.7 GeV nucleon~1 were measured by the Isotope Matter Antimatter Experiment (IMAX) during a Ñight from Lynn Lake, Manitoba, Canada on 1992 July 16È17. The IMAX balloon-borne magnetic spectrometer realized a direct measurement of the charge, the velocity, and the rigidity of cosmic rays using plastic scintillators, a high-resolution ti...
متن کاملCosmic-ray Sources and Source Composition
Present data on cosmic-ray elemental and isotopic relative abundances are shown to be unable to distinguish between various models of cosmic-ray sources and their composition. For example, the model of freshly nucleosynthesized material from supernova explosions as the cosmic-ray source is unable to account for some measured, key cosmic-ray elemental abundances. This and two other models are ev...
متن کاملGeomagnetic Field Eect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles
Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
