Abstract
Measurements have been made of the total cross sections of a number of elements for neutrons with a mean energy of 351.5 ± 2.0 MeV. The measured cross sections in millibarns were: Carbon 285.3 ± 1.6 Copper 1138 ± 9 Hydrogen 35.6 ± 0.7 Oxygen 366 ± 3 Tin 1887 ± 15 Deuterium 58.9 ± 1.0 Aluminium 565 ± 4.5 Lead 2828 ± 14 n-n 23.3 ± 0.7 A comparison with previous measurements shows that the total cross sections of complex nuclei remain constant within the experimental error 1% between neutron energies of 270 MeV and 380 MeV. At 410 MeV they have risen significantly due to meson production.Keywords
