摘要：
Pershore made CR-39(DOP) stack was exposed at a zenith angle of 30-degrees by Au-197-ions of energy 1.015 GeV/n using LBL BEVALAC beam. The top of the irradiated plate of the stack has been etched in 6.25N NaOH solution at 70-degrees-C for one hour. About 1202 cone lengths were optically measured. The estimated etch rate ratio of the incident Au-197 projectile beam in CR-39 has been found to be 27 +/- 2. The result has been compared with earlier observations. The charge resolution of the detector has been estimated from the average of double cone lengths and has been found to have a value of (0.58 +/- 0.03)e for Au-197-ions.
