物理吸附？
from space.com
When the solar wind, the rapid stream of charged particles emitted by the
sun, strikes the moon, helium 3 is deposited in the powdery soil. Over
billions of years that adds up. Meteorite bombardment disperses the
particles throughout the top several meters ofthe lunar surface.
powerdy soil应该是有利于吸附。

TiO2, fine-grained aggregates等等，应该是物理吸附在月壤颗粒上的

The helium-3 found in the lunar soil comes originally from the Sun. A stream
of particles from the Sun, called the solar wind, contains helium-3 which
is deposited on the Moon's surface.
...
The factors taken into account by the researchers in mapping the likely
abundance of helium-3 in a given area of the Moon are the exposure age of
the Moon's surface matter, or regolith; the amount
