Summbary

The possible existence of « negative-energy states » of positive-root solutions of the effective potential for a charged particle in an electromagnetic field superposed on black-hole space-times is presented. Though, in general, such states occur for particles contrarotating with respect to the black hole, indications are there that in some cases corotating particles also might show the existence of such states very close to the event horizon.

Riassunto

Si presenta la possibile esistenza di « stati ad energia negativa » di soluzioni a radice positiva del Potenziale efficace per una particella carica in un campo elettromagnetico sovrapposto a spazi-tempo del buco nero. Sebbene, in generale, tali stati si verifichino per particelle a rotazione contraria rispetto al bnco nero, ci sono indicazioni che in alcuni casi anche particelle corotanti potrebbero mostrare l’esistenza di tali stati molto vicino all’orizzonte degli eventi.
