摘要:

This article traces the development of optical pumping from the ideas first elaborated by Kastler in 1950. It deals with the general characteristics of optical pumping, the optical ‘magnetization’ of gases and vapours, spin exchange, metastability exchange, orientation by collision, multiple quantum resonances, atomic coherences, quantum beats, and dressed atoms: and concludes with a note on laser spectroscopy.

摘要:

Astronomers in Britain have until very recently found it hard to obtain observing time on large optical telescopes. The success of observational X-ray and radio astronomy has revealed an urgent need for first-class telescopes on excellent sites. That need is now being met in Australia and at the new observatory on the island of La Palma, where the Royal Greenwich Observatory is providing three telescopes for the Science Research Council. The largest of these, 4.2m in diameter, is to be named the William Herschel Telescope in commemoration of the great telescope builder and observer.

摘要:

Large electrical generating stations are not built in a day; 6 to 20 years might elapse between the decision to build and the satisfactory operation of a station. The C.E.G.B. has tried to ensure that enough generating capacity is available to avoid ‘power-cuts’ at all seasons and this brief account explains the hazards, the failures and the successes of the forecasts which have had to be made over the years. There have been many available options for the generation of electricity and the way ahead for the last decades of the Century is forecast.
