摘要：

A search has been made on the charge-changing partial cross-sections by using 0.927 GeV/n U-238 ion from LBL BEVALAC projected at an angle 30-degrees on Al-27 target and CR-39 (DOP) was used as analyser. The irradiated plastic sheets were duly etched for one hour in 6.25N NaOH solution and about 1680 cone lengths at both the surfaces of the CR-39 (DOP) sheets were optically measured. The cone length distribution exhibits the existence of U fragments in the charge range 84 less-than-or-equal-to Z less-than-or-equal-to 91 and the estimated partial cross-sections range from 60 to 400 mb. The present data are in accord with the fit to the extrapolated data of Binns et al.
