Photodissociation and photoionisation of atoms and molecules of astrophysical interest [PDF]

open access: yes, 2017
A new collection of photodissociation and photoionisation cross sections for 102 atoms and molecules of astrochemical interest has been assembled, along with a brief review of the basic processes involved.

Vibrationally mediated photodissociation dynamics of pyrrole

open access: yesAIP Advances, 2019
We investigate photodissociation of vibrationally excited pyrrole molecules in a velocity map imaging experiment with IR excitation of N–H bond stretching vibration v1 = 1, νIR= 3532 cm−1, and UV photodissociation at λUV= 243 nm. In the IR+UV experiment,

Formation of a gate dielectric of nanometer thickness by rapid thermal treatment

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2021
Investigations of the thickness and optical characteristics of thin SiO2 films obtained by one-, two-, or three-stage rapid thermal processing (RTP) at atmospheric pressure, pulses of 6, 12, and 20 s duration have been carried out.

Selective photodissociation of tailored molecular tags as a tool for quantum optics

open access: yesBeilstein Journal of Nanotechnology, 2017
Recent progress in synthetic chemistry and molecular quantum optics has enabled demonstrations of the quantum mechanical wave–particle duality for complex particles, with masses exceeding 10 kDa.

Experimental Study of the Laser-Induced Oxyhemoglobin Photodissociation in Cutaneous Blood Vessels

open access: yesActa Medica Bulgarica, 2015
A new optical method for reduction of local tissue hypoxia is proposed. It is shown that this method of phototherapy allows the control of a local oxygen concentration in tissue.

An ion trap source of cold atomic hydrogen via photodissociation of the BaH+ molecular ion

open access: yesNew Journal of Physics, 2022
I present a novel scheme for producing cold (magnetically trappable) atomic hydrogen, based on threshold photodissociation of the BaH ^+ molecular ion.

Structure of Stationary Photodissociation Fronts [PDF]

open access: yes, 1996
The structure of stationary photodissociation fronts is revisited. H_2 self- shielding is discussed, including the effects of line overlap. We find that line overlap is important for N(H_2) > 10^{20} cm^{-2}.

Jitter-correction for IR/UV-XUV pump-probe experiments at the FLASH free-electron laser

open access: yesNew Journal of Physics, 2017
In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can

Spectroscopy of Rb$_{2}$ dimers in solid $^{4}$He [PDF]

open access: yes, 2006
We present experimental and theoretical studies of the absorption, emission and photodissociation spectra of Rb$_{2}$ molecules in solid helium. We have identified 11 absorption bands of Rb$_{2}$.

Photodestruction of Diatomic Molecular Ions: Laboratory and Astrophysical Application

open access: yesMolecules, 2020
In this work, the processes of photodissociation of some diatomic molecular ions are investigated. The partial photodissociation cross-sections for the individual rovibrational states of the diatomic molecular ions, which involves alkali metals, as well ...
