摘      要：The photodetachment of a homo-nuclear linear tetra-atomic negative molecular ion is studied theoretically for an arbitrary laser *** expression for the total cross section is obtained by using an extended version of the two center model,where each center acts as a source of coherent photodetached-electron *** oscillations on observation plane,placed at a large distance from the ion,are *** amplitude of these oscillations is maximum when the laser polarization is parallel to the molecular ***,the amplitude decreases as the angle between the laser polarization and molecular axis increases and consequently vanishes when they are perpendicular to each *** is also found that if the distance between the adjacent centers is very small or very large,then the ampplitude of oscillations is negligibly small.
