    • Abundances of heavy and ultraheavy ions in ³He-rich solar flares 

      Mason, Glenn M.; Mazur, Joseph E.; Dwyer, Joseph R.; Jokipii, Jack Randy; Gold, Robert E.; Krimigis, Stamatios M. (2004-05-01)
      We have surveyed ³He-rich solar energetic particle (SEP) events over the period 1997 September-2003 April in order to characterize abundances of heavy ions near 400 keV nucleonˉ¹. The first part of the study focuses on 20 ...
    • Perpendicular transport of solar energetic particles in heliospheric magnetic fields 

      Zhang, Ming; Jokipii, Jack Randy; McKibben, Robert Bruce (2003-09-20)
      This paper presents direct observational evidence for large perpendicular diffusive flows of solar energetic particles in heliospheric magnetic fields. Using anisotropy measurements of 40-92 MeV protons obtained by the ...
