Franck-Condon effects in collision-induced electronic energy transfer: I2(E; v = 1,2) + He, Ar.
Collisions of I2 in the E electronic state with rare gas atoms result in electronic energy transfer to the D, beta, and D' ion-pair electronic states. Rate constants for each of these channels have been measured when I2 is initially prepared in the J = 55, nu = 1 and 2 levels in the E state. The rate constants and effective hard sphere collision cross sections confirm the trends observed when n...
متن کاملCrossed Molecular Beam Study of Collision-induced Dissociation of Alkali Halides*
Recent studies by Berry et al. [1,2] of collisional dissociation of alkali halides by shockheated argon have shown that, in vibrationallyequilibrated gases, some alkali halides (all cesium, rubidium and potassium salts except RbI and KI) dissociate completely to ion pairs, although dissociation to neutral atoms requires less energy. An e_xpression for the branching ratio for the different disso...
متن کاملTorsional effects in molecular alignment
A detailed theoretical formalism for the calculation of energy levels and eigenfunctions of molecules with a large amplitude coordinate in the presence of a strong laser pulse is developed based on a discrete variable representation to setup the Hamiltonian matrix. This approach is applied to nonrigid biphenyl-like molecules displaying a large amplitude motion corresponding to respective rotati...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Electron-Collision-Induced Alignment of Rare Gases near Threshold
Results of a semirelativistic R-matrix calculation are compared with experimental values for light polarizations and alignment parameters of the second excited-state manifolds of neon and krypton following electron impact excitation. The calculations focus on the near-threshold regime, where negative-ion resonances have a significant effect on the atomic alignment. A grouping of the alignment v...
