dc.description.abstract | The paper explores the numerical stability and the computational efficiency of a direct method for unfolding
the resolution function from the measurements of the neutron induced reactions. A detailed resolution function
formalism is laid out, followed by an overview of challenges present in a practical implementation of the method.
A special matrix storage scheme is developed in order to facilitate both the memory management of the resolution
function matrix, and to increase the computational efficiency of the matrix multiplication and decomposition
procedures. Due to its admirable computational properties, a Cholesky decomposition is at the heart of the
unfolding procedure. With the smallest but necessary modification of the matrix to be decomposed, the method
is successfully applied to system of 105 × 105
. However, the amplification of the uncertainties during the direct
inversion procedures limits the applicability of the method to high-precision measurements of neutron induced
reactions. | es |
