N. Koyumdjieva et al., CHARACTERISTIC FUNCTIONS IN THE STATISTICAL R-MATRIX THEORY, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 353(1), 1995, pp. 31-34
The characteristic functions of the statistical Wigner's R-matrix for
the case of one-channel scattering in competition with multichannel ra
diative capture have been drown. Different approximations and their re
levance in neutron physics applications are discussed.
