Atomic data for astrophysics: Ni XV [PDF]

Astronomy & Astrophysics, 2014
We present a new large-scale R-matrix scattering calculation for electron collisional excitation of Ni xi, carried out with the intermediate-coupling frame transformation method. The target includes all the main configurations up to n = 4, and is a significant improvement over earlier R-matrix (only three n = 3 configurations) and distorted-wave (DW ...

Assessment of atomic data: problems and solutions [PDF]

, 2013
For the reliable analysis and modelling of astrophysical, laser-produced and fusion plasmas, atomic data are required for a number of parameters, including energy levels, radiative rates and electron impact excitation rates.

Study of (n,2n) reaction cross section of fission product based on neural network and decision tree models [PDF]

EPJ Web of Conferences
The neutron induced nuclear reaction cross sections of fission products are related with the neutron fiux and the reactor burnup, which are important for the accurate of nuclear engineering design. To predict the (n,2n) reaction cross section, especially

Atomic Data - A Bibliography [PDF]

Symposium - International Astronomical Union, 1993
Space does not allow for a discussion of methods here. The reader is referred to the reviews or critical evaluations in the relevant sections. The current bibliography is an attempt to update the evaluations/reviews through to June 1992. Note that the Opacity Project provides an enormous amount of LS-coupling radiative data (see the Opacity Workshop ...

Measurement of Gamma-Ray from Inelastic Neutron Scattering on 56Fe [PDF]

EPJ Web of Conferences, 2020
In nuclear reactors, inelastic neutron scattering is a significant energy-loss mechanism which has deep impacts on designments of nuclear reactor and radiation shielding. Iron is an important material in reactor.

Precise Atomic Data [PDF]

Symposium - International Astronomical Union, 1988
We discuss the three questions: Why do we need accurate atomic data for stellar spectroscopy? What accuracy is needed? And: How can the accuracy of oscillator strengths be assessed? In conclusion we comment on the state of the art, stress the importance of uncertainty estimates and also discern between precision and accuracy.
