| Zusammenfassung |
| The PAMELA experiment has been collecting data since 2006; its results
indicate a rise in the positron fraction with respect to the sum of electrons
and positrons in the cosmic-ray (CR) spectrum above 10 GeV. This excess can
be due to additional sources, as SNRs or pulsars, which can lead to an
anisotropy in the local CR positron, detectable from current experiments. We
report on the analysis on spatial distributions of positron events collected
by PAMELA, taking into account also the geomagnetic field effects. No
significant deviation from the isotropy has been observed. |
