Employing recently developed magneto-optical trap recoil ion momentum spectroscopy(MOTRIMS) combined with cold atoms,strong laser pulse,and ultrafast technologies,we study momentum distributions of the multiply ionized cold rubidium(Rb) induced by the elliptically polarized laser pulses(35 fs,1.3×1015 W/cm2).The complete vector momenta of Rbn+ ions up to charge state n=4 are recorded with extremely high resolution(0.12 a.u.for Rb+).Variations of charac... 相似文献
