# Pair production in a magnetic and radiation field in a pulsar magnetosphere

## TL;DR

This paper investigates one- and two-photon pair production mechanisms in pulsar magnetospheres, highlighting the significance of resonant two-photon production as a potentially dominant plasma generation process.

## Contribution

It introduces the resonant two-photon pair production process as a novel mechanism in pulsar magnetospheres, expanding the understanding beyond traditional one-photon production.

## Key findings

- Resonant two-photon production cross section is significantly higher than nonresonant cases.
- Resonant two-photon process may be a key plasma generation mechanism in pulsars.
- One-photon production remains the primary known process.

## Abstract

In the present work one- and two-photon pair production in a subcritical magnetic field have been considered. Two-photon production has been studied in the resonant case, when the cross section considerably increases compared to the nonresonant case. While one-photon pair production is considered to be the main mechanism of plasma generation in a pulsar magnetosphere, we suggest the existence of another one, which is resonant two-photon production process.
