multiconfigurational calculations of experimentally significant energy levels and transition rates in Lr I
Joseph S. Andrews, Andrey I. Bondarev, Per Jönsson +4
Large-scale multiconfigurational calculations are conducted on experimentally significant transitions in Lr I and its lanthanide homologue Lu I, exhibiting good agreement with rece…
Targeted optimization in small-scale atomic structure calculations: application to Au I
Sema Caliskan, Jon Grumer, Anish M. Amarsi
The lack of reliable atomic data can be a severe limitation in astrophysical modelling, in particular of events such as kilonovae that require information on all neutron-capture el…
Extended MCDHF calculations of energy levels and transition data for N I
Meichun Li, Wenxian Li, P. Jönsson +2
Accurate and extensive atomic data are essential for spectroscopic analyses of stellar atmospheres and other astronomical objects. We present energy levels, lifetimes, and transiti…
A first spectroscopic measurement of the magnetic field strength for an active region of the solar corona
Ran Si, Tomas Brage, Wenxian Li +3
For all involved in astronomy, the importance of monitoring and determining astrophysical magnetic field strengths is clear. It is also a well-known fact that the corona magnetic f…
Resolving a discrepancy between experimental and theoretical lifetimes in atomic negative ions
Tomas Brage, Jon Grumer
Recently the lifetime of the excited -state of S was measured to be s (Bäckström et al. Phys. Rev. Lett. 114, 143003 (2015)). The earlier theoretical l…
A Novel Method to Determine Magnetic Fields in low-density Plasma e.g. Solar Flares Facilitated Through Accidental Degeneracy of Quantum States in Fe
Wenxian Li, Jon Grumer, Yang Yang +8
We propose a new method to determine magnetic fields, by using the magnetic-field induced electric dipole transition $3p^5\, ^2\mathrm{P}…
