Bøger i The Lebedev Physics Institute Series serien

This volume contains two papers that review certain theoretical problems that have been studied in the Laboratory of Plasma Accelerators and Plasma Physics of the P.

In this volume are collected scientific research reports written in recent years at the Radio-Astronomy Laboratory in the field of radio-astronomical apparatus and methods of ob servation.

It is well known that luminescence is the term used to describe the excess radiation from a body over and above the thermal radiation and persisting for a time which greatly exceeds the period of a light vibration.
