Abstract

The VULCAN laser was used for investigating 7Li(p,n) 7Be reactions with the help of Cu and CH primary and LiF secondary targets. CR-39 plastic track detector measured the neutron yield which was 3×10 19 Wcm -2 for CH primary targets and up to 2×10 8 sr -1 for Cu primary targets. At various angles, the angular distribution of neutrons was measured that indicated a relatively anisotropic distribution of neutrons over 180°. The reactions were found to be fficient for neutron radiography on high repetition, table-top lasers.
