Attachment
The process in which two particles collide and stick together
forming a single complex particle. The most common attachment
process is the formation of a negative ion from electron attachment
to an atom or molecule. Some negative ions are unstable, however,
and cannot survive.
The usual measure for this process is the attachment coefficient,
which on the average is the fraction of a large number of collisions
that result in attachment. Typical values of this fraction run
from 1 in 10,000 to 1 in 1,000.
