Helium-3 and other solar wind volatiles are successfully implanted into the lunar regolith and retained due to surface physical properties and low thermal escape.
The retrieved literature directly supports the claim by discussing solar wind implantation processes, activation energies, and the resulting retention of light volatiles like hydrogen and helium-3 in the lunar regolith. Papers [0], [1], and [2] specifically address solar wind implantation and retention mechanisms, while none of the provided papers refute the statement.
