Neutron optical devices, such as neutron guides, apply mirrors where m
ultiple total reflections of neutrons takes place. Materials more ligh
t and flexible than glass have never been used as a substrate of the n
eutron mirrors. The present work deals with neutron reflectivity measu
rements performed for three nickel mirrors. While one of them is a gla
ss plate coated with a NiCr film, the other two mirrors are on plexigl
as substrates coated by either NiCr or Ni-58 films. The incident beam
covered a neutron wavelength range from 0.05-0.4 nm. The results of th
e present measurements are in favour of the idea of using acrylic glas
s as a substrate for nickel mirrors.
