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.
