As exposed to a uniform static electric field, the atom or molecule can be ionized, and the ionized electron is accelerated infinitely. However, the transverse momentum distribution of ionized electron on the plane perpendicular to the direction of the electric field becomes stable as it exceeds the parent ions. This transverse momentum distribution can be extracted from the asymptotic wavefunction solution to the static Schrodinger equation in the presence of electric field. In this study, we present an approach to numerically calculate this quantity in the two-dimensional plane and show that it can reflect the property as well as the symmetry of the orbitals from which the electron is ionized. The study is illustrated by the calculation of several atomic systems and excited states of molecular hydrogen ion.
