Description

Neutron reflectivities were determined for 300 nm thick films of natural nickel and nickel 58 coated on glass plates. The measurements were performed at glancing angles between 40' and 60'. The incident neutron beam from one of the ET-RR-1 reactor horizontal channels covered neutron wavelengths between 0.55 and 0.80 nm. It was found that nickel 58, because of the high value of its critical glancing angle, is more efficient as a neutron mirror than natural nickel. (orig.)

Abstract (German)

Das Neutronenreflexionsvermoegen von 300 nm dicken Schichten aus natuerlichem Nickel und Nickel 58 auf Glasplatten wurde bestimmt. Die Messungen wurden bei Glanzwinkeln von 40' bis 60' durchgefuehrt. Der einfallende Neutronenstrahl von einem der horizontalen Kanaele des Reaktors ET-RR-1 umfasste Neutronen-Wellenlaengen zwischen 0,55 und 0,80 nm. Es zeigte sich, dass Nickel 58 wegen des hohen Wertes seines kritischen Glanzwinkels als Neutronenspiegel wirksamer ist als natuerliches Nickel. (orig.)
