Photodetachment electron flux of H− in combined electric and magnetic fields with arbitrary orientation

Interference of the photodetached electron waves propagating in perpendicular electric and magnetic fields

“…Later, many researchers have used this semi-classical method to treat the detached electron's dynamics in different external fields, such as in parallel electric and magnetic fields [11][12][13]; in electric field or magnetic field near a surface [14][15][16][17]; in a uniform magnetic field, [18] in crossed electric and magnetic fields. [19] Unlike the case of the electron photodetached from H − ion in an electric field, where only two detached electron's trajectories emitted from the source negative ion can arrive at a same point on the detector plane. When the magnetic field is added, due to the interaction between the electron and the magnetic field, more than two detached electron's trajectories can arrive at a given point on the detector plane, which lead to an intricate interference pattern in the electron flux distributions.…”

Temporal interference driven by an oscillating electric field in photodetachment of H − ion

“…[14] Later, it was developed into studying the photodetachment of the negative ion in the coexistence of electric and magnetic fields. [15][16][17][18][19][20][21][22] In 2010, Zhao and Delos put forward a semiclassical open-orbit theory to study the photoionization microscopy of a Rydberg hydrogen atom in a static electric field. [23] Recently, Yang and Robicheaux et al extended this semiclasical method to the time-dependent electric field and studied the phtodetachment dynamics of negative ions in the time-dependent electric field.…”
