Bottle-like structure in fission fragment tracks observed in a gamma-irradiated CR-39 detector

摘要

A bottle-like structure was discovered in etched tracks of fission fragments recorded in the gamma-ray-irradiated CR-39 track detector. The etched track has a relatively larger pit radius near the etched surface and has a smaller one in the deeper layer. This indicates that the supply of oxygen from the air should control the damage formation process. (C) 2001 Elsevier Science Ltd. All rights reserved. [References: 12]
