Summary
We compute the electromagnetic radiation that is emitted by a scalar charge moving uniformly in a gravitational-wave background. We give closed-form differential cross-sections which are valid for any velocity of the charge and for any direction of incidence of the gravitational wave. The results indicate that a charged-particle beam may be used in principle as a direction-sensitive gravitational-wave antenna.
Riassunto
Si calcola la radiazione elettromagnetica ehe è emessa da una carica scalare che si muove uuiformemente in un sistema di onde gravitazionali. Si danno sezioni d’urto differenziali in forma chiusa valide per qualsiasi velocità della carica e per qualsiasi direzione di incidenza dell’onda gravitazionale. I risultati indicano che un fascio di particelle cariche può essore usato in linea di principio come antenna per le onde gravitazionali sensibile alla direzione.
