Abstract
The effect of placing the CR-39 track detector in a vacuum on the diameters of alpha-particle tracks in the 0.49-5.15-MeV energy range was investigate d. It was shown that the track diameters decreased at a pressure of similar to 10(-2) Torr; after 8-12 h presence in a vacuum, the diameters changed s ignificantly. Prolonged exposure to a vacuum and short-duration return to a tmospheric pressure resulted in virtually complete recovery of alpha-partic le.
