Angular Distributions for a Model System of Nonadiabatic Molecular Collisions: The Quenching ofNa*(3p)by<

Partial widths of feshbach funnel resonances in the Na(3p) � H2 exciplex

“…Numerical values of r, and E, were determined by a nonlinear least squares fit to a smoothed version of Eq. (9) where A, , , is chosen high enough that stable results are obtained. Actually, of course, the "smoothing" simply corresponds to picking the correct branch of the inverse tangent.…”

Dynamical Stereochemistry on Several Electronic States: A Computational Study of Na* + H2

“…[18][19][20][21][22][23][24][25][26][27][28][29][30][31] In particular, Hertel et al 12 have discussed intuitive models and suitable systems of coordinates for this collision. As seen by H 2 , the p orbital of the electronically excited Na atom is like a quadrupole, which may or may not lock along the molecular axis.…”

Molecular-beam scattering

“…The added symmetry of Cl« vs. HC1 causes some of the Ca-CU molecular states to not corre late with fluorescent product states. By varying the polarization, the Ca atoms can be preferentially directed on or off these dark potential surfaces.With this historical background, we have modified a scattering apparatus to study reactive collisions of Na(3 P,.-) following the[12][13][14][15][16][17][18][19][20][21] basic design configuration of Hertel, et alThe major differ ence between the two apparati is the scattered product detector.Hertel and coworkers use a hot wire filament, sensitive to alkali atoms, while in this case, an electron bombardment ionization univer sal mass spectrometer is used. The added flexibility of detecting 5 product at any mass comes with approximately a 10 loss in detection efficiency compared to the hot wire filament.…”
