Combining the results of the l upsilon q (q) over bar and q (q) over barq (q) over bar final states, cross section and mass exclusion limits are set for models that predict heavy spin-1 and spin-2 resonances.
When using pulse trains, the nonlinear response is mainly due to the accumulation of molecules in the cis configuration, which presents a ground state cross-section slightly smaller than that of trans.
Depending on the AlAs and InAs composition one can adjust the wavelength of SML QDs within 0.75 1.3 μm Figure 13 Empty state cross-section scanning tunneling microscopy image of the SML QD insertion taken at low positive sample bias.
Correspondingly, the two-photon (δ2) and excited-state cross-section (δe) values of b and c also were obtained, and value of them were 485 GM and 1.03 × 10−17 cm2 for b, and 1100 GM and 1.27 × 10−18 cm2 for c, respectively.
These molecules combine very large two-photon absorption cross-sections (with typical σ2p maximum values of 3 × 10−20 cm4 GW−1 at 735 nm) and large excited-state cross-sections (with typical maximum σe values of 5 × 10−16 cm2) in the red NIR region, as shown by two-photon-excited fluorescence and pump probe Kerr ellipsometry experiments.
Parameters such as saturation fluence, excited state absorption cross section and ground state absorption cross section of the samples have been determined numerically, from which the figure of merit for nonlinear absorption is calculated.
When the heat sink temperature of Nd YVO4 is fixed and the temperature of Cr4+:YAG is changed to adjust its ground state absorption cross section, the peak power and single-pulse energy are decreased by 50% and 30%, respectively, as the temperature increases from 0 to 170 °C.
On the one hand, the excited atom yield and, thus, the total metastable state excitation cross section as a function of impact energy are obtained.
They state: "The cross section hydraulics characteristics: average velocity V = 0.2 to 0.5 m/s, average depth D = 2 to 4.5 m and top width T = 200 to 250 m".

State-to-state scattering cross sections at a collision energy of 485cm−1 were calculated using the V sum and V dif PESs by Cybulski and Fernández [16].
