Comparison of elemental abundances in sun, meteorites and earth
provides understanding of the formation and evolution of the solar
system. Yet, the majority of the solar system abundances are based on
meteoritic values [1–6]. Here we report an attempt to estimate a feasibility
of direct measurements of iodine and bromine in the GENESIS solar
wind Aluminum on Sapphire collector (AloS) using neutron induced
conversions: ^(127)I(n,γβ)^(128)Xe, ^(79)Br(n,γβ)^(80)Kr and ^(81)Br(n,γβ)^(82)Kr
