%TEstimation of thermal neutron cross sections from K, U, Th concentrations for rock samples using neural network algorithms
%XIn the paper present the results of the use of the neural network algorithms to find a function {Sigma}{sub a}=f(K, U, Th,...). The easily measurable parameters (K, U, Th concentrations, lithology) were used to estimate the thermal neutron absorption cross-section {Sigma}{sub a}, which is difficult to measure in the borehole conditions. This paper is suggesting a possible solution to the problem. This method may have an important application in the well-logging data treatment. (author). 6 refs, 9 tabs.
