Low Energy Deuteron-Triton Fusion Cross Sections: A Review of Experiments and Data Evaluations

Among these five sets of data, the data obtained from the windowless gas target experiments exhibit the highest quality, while the data from the heavy-ice target experiment and ultra-thin solid target experiments exhibit systematic deviations. This dataset presents, in chronological order, the experimental information, experiment data, and error analyses for these experiments. To convert the laboratory-frame differential cross sections to the center-of-mass-frame differential cross sections, a conversion factor must be applied.

The reference for the theory used to calculate this conversion factor is as follows:(1)B. Carlson, M. Goldstein, L. Rosen, D. Sweeney, The conservation of energy and momentum in nuclear reactions, 1949, LA-723(2)J. L. Fowler, John E. Brolley, Monoenergetic neutron techniques in the 10- to 30-MeV range. Rev. of Mod.

For ease of comparison, the equivalent deuteron-beam energy is also listed in the data, even when the experiment was performed using a triton beam.
