2003 review of neutron and non-neutron nuclear data.

چکیده
This paper reviews the scientific literature for new measurements of both non-neutron and neutron nuclear data. Some of the highlights of this review are the following items. There was a withdrawal of a previous claim for discovery of element 118. There have been new measurements of some isotopic abundance values that have led to changes for many elements. There was a new set of recommended standards for calibration of gamma-ray energies published for many nuclides. There have been new half-life measurements reported for very short lived isotopes, for many long-lived nuclides, and for half-lives of double beta (betabeta) decay measurements for quasi-stable nuclides. There was also a new reassessment reported of spontaneous fission (sf) half-lives for ground state nuclides, which distinguished between the half-lives from sf decay and from cluster decay and from the new cluster-fission decay process. This review reports on various nuclear interactions such as charged particle cross sections (n,p) and (n,alpha) measurements for thermal neutrons incident on light nuclides. New thermal (n,gamma) cross sections and neutron resonance integrals that have been measured or re-evaluated are also presented.

متن کاملEstimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user
Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
