Abstract
Observations are reported on the appearance of frustrated total reflec tion, i.e. the tunnelling phenomenon, with cold neutron wave-particles . This tunnelling resonance was observed in a thin film Ni-V-Ni Fabry- Perot cavity by time of flight grazing angle neutron reflectometry. Th is frustrated total reflection phenomenon was used to estimate the neu tron lifetime, which varies from approximately 0.1 to 1 mu s.
