Coupled Chemistry-Emission Model for Atomic Oxygen Green and Red-doublet Emissions in Comet C/1996 B2 Hyakutake

open access: yes, 2012
The green (5577 \AA) and red-doublet (6300, 6364 \AA) lines are prompt emissions of metastable oxygen atoms in the $^1$S and $^1$D states, respectively, that have been observed in several comets.

Near-IR photodissociation of peroxy acetyl nitrate [PDF]

open access: yesAtmospheric Chemistry and Physics, 2005
Measurements of the C-H overtone transition strengths combined with estimates of the photodissociation cross sections for these transitions suggest that near-IR photodissociation of peroxy acetyl nitrate (PAN) is less significant (Jnear-IR≈3x10-8s ...

Photodissociation of p-process nuclei studied by bremsstrahlung induced activation

open access: yes, 2005
A research program has been started to study experimentally the near-threshold photodissociation of nuclides in the chain of cosmic heavy element production with bremsstrahlung from the ELBE accelerator. An important prerequisite for such studies is good

PHOTODISSOCIATION OF PbCl2

open access: yesActa Physica Sinica, 1988
The population on 6p2 3P2 metastable state and 6p2 3P0 ground state of Pb atoms are de-monstrated, which are originated from dissociating PbCl2 by the fourth harmonic of YAG lasers. The population ratio of 3P2 to 3P0 is measured in terms of laser-induced fluorescence.

Simulating cold atomic hydrogen production in linear radiofrequency ion traps

open access: yesNew Journal of Physics
We simulated the motion of ${\mathrm{BaH^{+}}}$ molecular ions which are sympathetically cooled by laser-cooled ${\mathrm{Ba^{+}}}$ ions in linear quadrupole and octupole radiofrequency (RF) ion traps.

Indistinguishability and Interference in the Coherent Control of Atomic and Molecular Processes

open access: yes, 2010
The subtle and fundamental issue of indistinguishability and interference between independent pathways to the same target state is examined in the context of coherent control of atomic and molecular processes, with emphasis placed on possible "which-way"

Structural characterization of holo- and apo-myoglobin in the gas phase by ultraviolet photodissociation mass spectrometry

open access: yesChemical Science, 2014
193 nm UV photodissociation of myoglobin in the gas phase showed preferential backbone cleavages in regions with higher relative B-factors.

Charge-transfer photodissociation of adsorbed molecules via electron image states

open access: yes, 2007
The 248nm and 193nm photodissociation of submonolayer quantities of CH$_3$Br and CH$_3$I adsorbed on thin layers of n-hexane indicate that the dissociation is caused by dissociative electron attachment from sub-vacuum level photoelectrons created in the ...
