Radiative decay of a massive particle and the non-thermal process in primordial nucleosynthesis [PDF]
, 2000 We consider the effects on big bang nucleosynthesis (BBN) of the radiative decay of a long-lived massive particle. If high-energy photons are emitted after the BBN epoch ($t \sim 1 - 10^3$ sec), they may change the abundances of the light elements ...

C60IN PHOTODISSOCIATION REGIONS [PDF]
The Astrophysical Journal, 2014 Recent studies have confirmed the presence of buckminsterfullerene (C$_{60}$) in different interstellar and circumstellar environments. However, several aspects regarding C$_{60}$ in space are not well understood yet, such as the formation and excitation processes, and the connection between C$_{60}$ and other carbonaceous compounds in the interstellar

Photodissociation of water in crystalline ice: a molecular dynamics study [PDF]
, 2005 Ultraviolet irradiation of ice is of great interest for understanding the chemistry in both atmospheric and astrophysical environments. In interstellar space, photodissociation of H2O molecules can be a driving force behind the chemistry on icy dust ...

Vibrationally mediated photodissociation dynamics of pyrrole
AIP 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,

Photodissociation Dynamics of DNA Bases [PDF]
Journal of Biological Physics, 2003 In order to access the damaging mechanismsof DNA and its bases on themolecular level by T Hz radiation, it isnecessary to create a database of assessingdamage at different spectral regions.Possible damage by T Hz radiation will beassessed by comparison.
