Abstract

Through solution of the multielectron, semi-relativistic, time-dependent Schrodinger equation, we show that angular streaking produces strongly spin-polarized electrons in a noble gas. The degree of spin polarization increases with the Keldysh parameter, so that angular streaking --- ordinarily applied to investigate tunneling | may be repurposed to generate strongly spin-polarized electron bunches. Additionally, we explore modications of the angular streaking scheme that also enhance spin polarization.
