Abstract

Various electronic states of Ba, from ground state up to 2.24 eV ({sup 1}S{sub 0}, {sup 3}D{sub J}, {sup 1}D{sub 2}, {sup 3}P{sub 1}, and {sup 1}P{sub 1}) together with Ba{sup +}({sup 2}P{sub 3/2}), were produced by 1064 nm high-irradiance pulsed nanosecond laser ablation of Ba in vacuum. The velocity distribution for every species was obtained from time-of-flight measurements, using pulsed laser induced fluorescence or time-resolved optical emission spectroscopy, as applicable to each species. The distributions are bimodal, Maxwell-Boltzmann functions for {sup 1}S{sub 0}, {sup 3}D{sub J}, and {sup 1}D{sub 2} and shifted Maxwell-Boltzmann for the rest of the states, with different peak velocities and average, hyperthermal translational temperatures. Possible mechanisms for the production of these velocity distributions are discussed.

Internal state populations and velocity distributions of monatomic species ejected after the 1064 nm laser irradiation of barium

Journal Article Rossa, Maximiliano; Rinaldi, Carlos; Ferrero, Juan - Journal of Applied Physics

The plumes accompanying 1064 nm nanosecond pulsed laser ablation of barium in vacuum at three moderate incident laser fluences in the range of 5.3-10.8 J/cm{sup 2} have been studied using both wavelength and time resolved optical emission spectroscopy and time-of-flight laser-induced fluorescence. Neutral atoms and both singly and doubly charged monatomic cations in excited states up to near the corresponding ionization limits are identified in the optical emission spectra. The population distributions of low-lying ({<=}1.41 eV) 'dark' states of Ba atoms measured by laser-induced fluorescence revel that the metastable {sup 3}D{sub J} and {sup 1}D{sub 2} abundances in the plumemore »« less

Zeeman cross sections [sigma][sub [ital j],][ital m[ital j]][r arrow][ital j][prime],[ital m][sub [ital j]][sup [prime]] for the spin-changing 6[ital s]6[ital p] [sup 1][ital P][sub 1]--6[ital s]6[ital p] [sup 3][ital P][sub 2] transition of barium induced by single collisions with N[sub 2], O[sub 2], and H[sub 2] have been measured using a crossed-beam apparatus. State-selective preparation of 6[ital s]6[ital p] [sup 1][ital P][sub 1,][ital m[ital j]] and detection of 6[ital s]6[ital p] [sup 3][ital P][sub 2,][ital m[ital j]][sup [prime]] was achieved using the laser excitation technique in the presence of a magnetic field that breaks the degeneracy of the magnetic sublevels.

Temperature dependence of the photodissociation of CO₂ from high vibrational levels: 205-230 nm imaging studies of CO(X¹Σ⁺) and O(³P, ¹D) products

Journal Article Sutradhar, S.; Samanta, B.; Samanta, A.; ... - Journal of Chemical Physics

In this paper, the 205-230 nm photodissociation of vibrationally excited CO₂ at temperatures up to 1800 K was studied using Resonance Enhanced Multiphoton Ionization (REMPI) and time-sliced Velocity Map Imaging (VMI). CO₂ molecules seeded in He were heated in an SiC tube attached to a pulsed valve and supersonically expanded to create a molecular beam of rotationally cooled but vibrationally hot CO₂. Photodissociation was observed from vibrationally excited CO₂ with internal energies up to about 20 000 cm^-1, and CO(X¹Σ⁺), O(³P), and O(¹D) products were detected by REMPI. The large enhancement in the absorption cross section with increasing CO₂ vibrationalmore »« less

Reaction dynamics from orbital alignment dependence and angular distributions of ions produced in collision of Ba( sup 1 P ) with NO sub 2 and O sub 3

Journal Article Suits, A; Hou, H; Davis, H; ... - Journal of Chemical Physics; (United States)

Angular distributions, orbital alignment dependence, and energy dependence of the relative cross sections of various ions produced in crossed beams collisions of electronically excited barium with O{sub 3} and NO{sub 2} were used to explore the dynamics of these reactions. The Ba{sup +} product from both reactions showed strong dependence on alignment of the Ba({sup 1}{ital P}) {ital p} orbital with respect to the relative velocity vector. The Ba{sup +} was generally forward or forward-sideways scattered, with the latter favored by the dominant perpendicular orbital alignment. Similar results for Ba{sup +} from both O{sub 3} and NO{sub 2} suggest thatmore »« less

Polarization effects in the differential cross section of the Ba( sup 1 P sub 1 - sup 3 P sub 2 ) inelastic transition induced by argon

Journal Article Visticot, J; de Pujo, P; Sublemontier, O; ... - Physical Review A. General Physics; (United States)

The Ba(6{ital s}6{ital p} {sup 1}{ital P}{sub 1}{r arrow}{sup 3}{ital P}{sub 2}) inelastic transition induced by argon has been investigated in a crossed beam as a function of the collision energy between 0.14 and 0.40 eV. The differential cross sections have been obtained by the Doppler technique probing the Ba(6{ital s}6{ital p} {sup 3}{ital P}{sub 2}) with a single-mode cw laser. Oscillations are observed in the differential cross sections that are assigned to Stueckelberg interferences resulting from a crossing between the {sup 1}{Pi}{sub 1} and {sup 3}{Sigma}{sub 1} Ba-Ar potential-energy curves. A very large polarization effect is observed by comparingmore »« less
