Summary

The properties of electromagnetic and gravitational multipole radiation are compared. The gravitational field and its interaction with matter is treated within the scope of the linearized theory. Application is made to the emission and absorption of gravitons by microscopic systems such as molecules and nuclei. Processes leading to their production and detection are described. The intensity of gravitational radiation resulting from such processes taking place in celestial bodies is determined. The possibility of increasing the graviton flux by stimulated emission is discussed.

Riassunto

Si confrontano le proprietn della radiazione di multipolo elettromagnetico e gravitazionale. Si discute il campo gravitazionale e la sua interazione con la materia entro il campo di applicazione della teoria linearizzata. Si fanno delle applicazioni aU’emissione ed assorbimento di gravitoni da parte di sistemi microscopici come molecole e nuclei. Si descrivono dei processi che portano alia loro produzione e rivelazione. Si determina l’intensita della radiazione gravitazionale clie risulta da quei processi che lianno luogo nei corpi celesti. Si discute la possibility di accrescere il flusso di gravitoni tramite emissione stimolata.
