Change of Electrical Conductivity of Sodium Chloride upon Bombardment with High-Energy Protons

Abstract

The conductivity of NaCl in the region 125°C to 400°C is considerably decreased by bombardment at room temperature with ${10}^{15}$ protons/${\mathrm{cm}}^2$ of energy 350 Mev. There are several temperatures where part of the effect anneals. A small decrease in conductivity still remains after heating to as high as 470°C. No satisfactory explanation for the results is evident.
