Cold neutron interferometry and its applications. 1. Coherency and cold neutron spin interferometry

The workshop entitled 'Interference studies and cold neutron spin interferometry' was held on 26 and 27 August 1997 at KUR(Kyoto University Research Reactor Institute, Kumatori). Cold neutron spin interferometry is a new field. So it is very important for its development to learn the studies of X-ray and neutron optics which are rapidly developing with long history. In the workshop, the issues related to interference were reviewed such as experimental studies on cold neutron spin interferometry, theoretical and experimental approach on tunneling time, interference experiments by neutrons and its application, interference studies using synchrotron radiation, Topics on silicon interferometry and quantum measurement problem and cold neutron interference experiment related to quantum measurement problem. The 12 papers are indexed individually. (J.P.N.)
