Cui Hui-Fang^{1, 2}, Miao Xiang-Yang^{1, 2, †}

Photoelectron momentum distributions of the model atom in panels (a)–(d) co-rotating polarization case and (e)–(h) counter-rotating polarization case at different ellipticities: (a) and (e) ε = 0, (b) and (f) ε = 0.25, (c) and (g) ε = 0.5, and (d) and (h) ε = 0.75. Panels (i) and (j) show theoretical results of the parameter | A_γ|² in co-rotating polarization case and counter-rotating polarization case, respectively.
