Paper Abstract

We theoretically study the photoelectron momentum distributions of the negative hydrogen ions by a pair of time-delayed circularly polarized laser pulses. It is found that the multi-arm helical vortex structures appear in the photoelectron momentum distributions. Moreover, the vortex structures can be adjusted by the laser parameters. The present work is meaningful for the optical control of the laser-induced detachment of negative ions.
