Ultracold Neutrons
Ultracold Neutrons is a guide to a fascinating topic. It describes how a simple new idea in experimental neutron physics has changed the landscape of what is often called 'fundamental physics.' Ultracold neutrons (UCNs) are neutrons moving at the low speed of a bicycle rider. They were produced for the first time 50 years ago (in 1968) and are distinguished from ordinary neutrons with much higher energies by their ability to be confined in 'neutron bottles' for durations up to several hundred seconds. This is possible since they are reflected back and forth from the container walls many thousands of times with very little loss. As a result of these long observation times, their properties and interactions with the environment can be studied with superb precision.Directed towards a general readership, this book is an excellent introduction to a field of research that is not highly specialized but touches on many aspects of our physical world, classical as well as quantum mechanical.<b>Contents:</b> <ul><li>Introduction</li><li>The Early History of Very Low Energy Neutrons</li><li>Neutron Interactions Relevant in the UCN Energy Range</li><li>Sources of Ultracold Neutrons</li><li>Total Cross-Section Measurements with Very Low Energy Neutrons</li><li>UCN and VCN Reflection, Transmission and Scattering at Material Walls</li><li>Neutron Optical Experiments Probing the Wave Properties of Ultracold Neutrons</li><li>High-Resolution UCN Spectroscopy</li><li>Possibility of Microscopy and Interferometry with Ultracold Neutrons</li><li>Gravitational Quantum States of the Neutron</li><li>Measurement of the Neutron Lifetime for Beta Decay</li><li>Search for the Electric Dipole Moment of the Neutron Using Stored Ultracold Neutrons</li><li>Further UCN Applications in Fundamental Physics</li><li>Appendices</li></ul><br><b>Readership:</b> General audience with interest in fundamental physics.
