Abstract

Evaluated half-life values are given for the radionuclides sup 2 sup 6 Al, sup 4 sup 0 K, sup 5 sup 3 Mn, sup 6 sup 0 Fe, sup 8 sup 7 Rb, sup 9 sup 3 Zr, sup 9 sup 8 Tc, sup 1 sup 0 sup 7 Pd, sup 1 sup 2 sup 9 I, sup 1 sup 3 sup 5 Cs, sup 1 sup 4 sup 6 Sm, sup 1 sup 7 sup 6 Lu, sup 1 sup 8 sup 2 Hf, sup 1 sup 8 sup 7 Re, sup 2 sup 0 sup 5 Pb, sup 2 sup 3 sup 2 Th, sup 2 sup 3 sup 5 U, sup 2 sup 3 sup 8 U, sup 2 sup 4 sup 4 Pu and sup 2 sup 4 sup 7 Cm. These were obtained from an analysis of published information up to 2001. These half-lives are used in geochronology and cosmochronology to determine different radiometric ages in the history of the earth, solar system and galaxy.

26. New evaluation of the characteristics of the decay and radiations of the Au radionuclide.

Author

Chechev, V. and Kuzmenko, N.

Abstract

Newly evaluated (recommended) values of the decay and radiations of the Au radionuclide, obtained with allowance for the information published up to 2014, are presented. The evaluation is performed as part of the DDEP (Decay Data Evaluation Project) program for international cooperation in research work. [ABSTRACT FROM AUTHOR]

Abstract

The International Chart of Nuclides — 2003 has been developed taking into account the data obtained in 1998 – 2003. Unlike widespread nuclide charts the present Chart of Nuclides contains EVALUATED values of the main characteristics. These values are supplied with the standard deviations. The presented data are applicable in medicine, agriculture, environmental protection etc. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

34. Search for an optimum approach to the evaluation of data of varying consistency: half-live evaluations for 3H, 35S, 55Fe, 99Mo and 111In.

Abstract

A common procedure is proposed for the evaluation of both consistent and discrepant data in which adjustments are made to the uncertainties in the measured data that are dependent on the chi2 values of the data set. A computer program EVINEW has been developed and applied to the evaluation of 3H, 3S, 55Fe, 99Mo and 111In half-lives to give the following values: 12.32(2) yr, 87.32(16) d, 2.732(14) yr, 2.7480(9) d and 2.8047(4) d, respectively.
