Atomic data for neutron-capture elements II. Photoionization and recombination properties of low-charge krypton ions
atomic data - atomic processes - HII regions - nucleosynthesis, abundances - planetary nebulae: general - stars:evolution
2011/10/12
We present multi-configuration Breit-Pauli distorted-wave photoionization (PI) cross sections and radiative recombination (RR) and dielectronic recombination (DR) rate coefficients for the first six k...
Towards a complete treatment of the cosmological recombination problem
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/7
A new approach to the cosmological recombination problem is presented, which completes our previous analysis on the effects of two-photon processes during the epoch of cosmological hydrogen recombinat...
Radio Recombination Lines at Decametre Wavelengths: Prospects for the Future
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO) Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/23
This paper considers the suitability of a number of emerging and future instruments for the study of radio recombination lines (RRLs) at frequencies below 200 MHz. These lines arise only in low-densit...
Statistical universal branching ratios for cosmic ray dissociation, photodissociation, and dissociative recombination of the C(n=2-10), C(n=2-4)H and C3H2 neutral and cationic species
Galaxy Astrophysics (astro-ph.GA)
