for which high-energy beam (50–300 keV) has been essential to promote creations of precu

such as voids or vacancy aggregates for initial confinements of noble-gas atoms. Therefore

the present low-energy implantation implies that the argon confinements have occurred at pre-existing low-density regions in the glass matrix
