Enhancement of γ -Ray Absorption in the Radiation Field of a High-Power Laser

This paper reports an analytic estimate of the cross section for the absorption of a gamma-ray photon when the nuclear recoil is compensated by the simultaneous absorption of an optical photon from the radiation field of a high-power laser. A multiphonon transition model is developed, and cross sect...

Description
Summary:This paper reports an analytic estimate of the cross section for the absorption of a gamma-ray photon when the nuclear recoil is compensated by the simultaneous absorption of an optical photon from the radiation field of a high-power laser. A multiphonon transition model is developed, and cross sections of the order of 1 sq fm are obtained when nearly resonant intermediate states of nuclear excitation are assumed to lie within a few tens of eV of the transition energy.
