Additions and corrections to the communications presented by France at the Geneva Conference in august 1955; Additifs et correctifs aux communications presentees par la France a la conference de Geneve d'aout 1955

Abstract

A graphic correction is given for the communication number 442 of the C.E.A. at the Geneva conference about the measurement of atmosphere radioactivity and pollution near an atomic centre. An addition to the communication number 446 of the C.E.A. at the Geneva conference about the measurement of the cross section of fissile nucleus for slow neutrons is presented. It discussed the measurement of the cross section of {sup 235}U nucleus fission for neutrons of 25 keV by comparing the fission cross section of {sup 235}U and the activation cross section of {sup 197}Au with two different neutrons sources. The principle and experimental procedures are explained and the experimental data and results are given. A note about the cross section of {sup 239}Pu fission for slow neutrons is added. A modification of the appendix in the communication number 405 of the C.E.A. at the Geneva conference about the study of the energy dependent variation of the cross sections of {sup 233}U, {sup 235}U and {sup 239}Pu fission for fast neutrons is given. The variation of the fission cross sections of {sup 233}U, {sup 235}U and {sup 239}Pu with the neutrons energy is given as well as the variation of the counting  More>>

The efficiency of the 'long' counter is discussed. (M.P.)}
