摘要:

A new method for the measurement of the density‐radius product (&rgr;R) of laser‐imploded plasmas is presented. Deuterium‐tritium‐hydrogen fuel mixture is used and the spectrum of protons elastically scattered by 14.1 MeV neutrons is measured with nuclear emulsion. The reliability of this method was certified by comparing the inferred &rgr;Rvalue with that from the secondary reaction method in equivalent experimental conditions.
