Profilometer step-height measurements, ion-beam analysis, and electron microscopy have been used to characterize the structural changes and hydration of argon, krypton, and xenon implanted fused silica and soda-lime glass. For both glasses, a structural change from a compacted to an expanded state occurs for energy deposition values near 10(23) keV/cm(3). This change occurs due to the break-down of the three-membered ring structure, formed near 10(20) kev/cm(3), by continuing implantation damage and bond-breaking by ambient atmospheres.

Abstract
Profilometer step-height measurements, ion-beam analysis, and electron microscopy have been used to characterize the structural changes and hydration of argon, krypton, and xenon implanted fused silica and soda-lime glass. For both glasses, a structural change from a compacted to an expanded state occurs for energy deposition values near 10(23) keV/cm(3). This change occurs due to the break-down of the three-membered ring structure, formed near 10(20) kev/cm(3), by continuing implantation damage and bond-breaking by ambient atmospheres.
