Neutron intensity transmitted through a multi-capillary fiber was measured
as a function of neutron wavelength. Transmission rate was independent of c
urvature of the fiber above about 5 Angstrom, and below this wavelength the
ratio became small with decreasing the radius of the curvature. A fiber wh
ich consisted of 15 mu m capillaries gave higher intensity than that of 10
mu m. (C) 2000 Elsevier Science B.V. All rights reserved.
