Abstract
The transmission sputtering ratio for protons in
monocrystalline silver foils was determined over the
energy range from 250 KeV to 700 KeV and found to
be approximately .01 for the {111} orientation. The
sputtering ratio was found to be an insensitive function
of proton energy and target thickness.
Target films were prepared by epitaxial growth on
the {111} cleavage face of lithium fluoride substrates,
and were approximately 98% oriented. Film thickness varied from 11,300Å to 30,600Å.
Sputtered silver was collected on pyrolitic graphite,
irradiated in a thermal neutron flux of 4.5 x 10¹⁰ neutron/
cm²/sec and detected by computer analysis of the resulting
decay curves.
Preferential ejection of protons and silver atoms
along low index directions of the targets and radiation
damage effects were observed.
