An ultraintense Gaussian (1,0) mode pulsed laser applied to laser-plasma electron acceleration is investigated based on 2.5-dimensional particle-in-cell simulation (PIC). It has been found that Gaussian (1,0) mode laser pulse may blow out plasma electrons and form two symmetrical electron cavities with an electron wall between them. This electron wall separates two twisting bunches of transverse injected electrons and lets each of them be accelerated in one cavity, respectively. At the front of the wall, a bunch of reflux electrons with a magnetic field contributes to the electron self-bunching effect. This mechanism may generate two symmetrical, high-density, and monoenergetic electron beams with small transverse emittances.
