Neutron Cross Sections for Some Threshold Reactions
Three neutron reactions leading to production of the rare gases Ar41 and Xe135 have been in vestigated. Single crystal samples of KF, CaF2 , and BaF2 were irradiated in the Berlin reactor and the target-free absolute activities of the rare gas isotopes measured by a /^-/-coincidence method. The calculated cross sections are K41 (n,p)Ar41: o = ( 2 ,73±0,41) mb; o0= (98,6± 14,8) mb; Ca44(n,a)Ar4...
متن کاملDosimetry in Mixed Neutron-Gamma Fields
The gamma field accompanying neutrons may, in certain circumstances, play an important role in the analysis of neutron dosimetry and even in the interpretation of radiation induced steel embrittlement. At the figh Flux Isotope Reactor pressure vessel the gamma-induced reactions dominate the responses of ' W p and 238u dosimeters, and9Be helium accumulation fluence monitors. The gamma induced at...
متن کاملNeutron Cross Sections for Nucleosynthesis Studies
Previous compilations of (n, γ ) cross sections of relevance for neutron capture nucleosynthesis in the big bang and in the slow neutron capture process (s process) have been updated to encompass information available up to December 1998; data references include work in process then and published subsequently. The experimental results for nuclei between H and Bi were critically surveyed, renorm...
متن کاملNeutron dosimetry
R É S U M É En dosimétrie des neutrons, les situations pratiques rencontrées couvrent un large domaine d'énergie s'étendant sur plus de 10 décades. En outre, les grandeurs dosimétriques utilisées en radioprotection ne sont pas directement accessibles à la mesure. Ce dernier point est principalement dû à la variation de la "qualité" du rayonnement neutronique, exprimé au moyen des facteurs de po...
متن کاملNormalization of neutron-proton differential cross sections
The np differential cross section below 350 MeV neutron laboratory energy is studied using the energy-dependent Nijmegen partial-wave analysis PWA93. We analyze in detail three experiments, performed at LAMPF, at TRIUMF, and at the TSL facility in Uppsala. The issue of normalization of np cross sections is discussed, where we distinguish between measured and calculated normalizations. This anal...
