This paper reports an analytic estimate developed from a multiphoton model of the cross section for the absorption of a $\ensuremath{\gamma}$-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. Tabulated data show 22 experimentally accessible nuclear transitions which might be expected to demonstrate this effect.NUCLEAR REACTIONS Calculated $B(E1)$ for multiphoton absorption; $\ensuremath{\gamma}$+optical photon from laser.
