Abstract:
We investigate the long-term evolution of D2+ nuclear wave-packet after interacting with a 5 fs, 800 nm laser pulse at an intensity of 0.5 x 10(14) W/cm2. The nuclear wave-packet evolves in field-free condition for very long time after the laser pulse. The collapse and revival of nuclear wave-packet is studied. The scale of the classical time (approximately 25 fs), the revival time (approximately 580 fs) and the super-revival time (approximately 12 ps) are determined from the simulation as well as the calculation. The constituents of long-standing nuclear wave-packet are also analyzed.

Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.
