Photoelectrons ionized from atoms and molecules in a strong laser field are either emitted directly or rescattered by the nucleus, both of which can serve as efficiently useful tools for molecular orbital imaging. We measure the photoelectron angular distributions of molecules (N2, O2 and CO2) ionized by infrared laser pulses (1320 nm, 0.2 ~ 1 × 10(14)(More)
The paper gives a new value model based on rough set and fuzzy theory to value the companies' customer relationship management. Because the number of customer relationship management' indices is too many and the calculation is very complex, this paper uses rough set to play down the complication.
