Abstract:
Electron-impact excitation collision strengths are required for the
analysis and interpretation of stellar observations.
This calculation aims to provide effective collision strengths for the
MgV ion for a larger number of transitions and for a greater
temperature range than previously available, using collision strength
data that include contributions from resonances.
Description:
The effective collision strengths are presented in this table for all
transitions among the lowest 37 fine-structure levels belonging to the
2s(2)2p(4), 2s2p(5), 2p(6), 2s(2)2p(3)3s and 2s(2)2p(3)3pl
configurations of Mg V.
These have been calculated using the Breit-Pauli R-matrix method. Each
fine-structure level is assigned an index number in Table 6 of the
manuscript ranging from 1 to 37. These index values are used here in
Table 8 to refer to particular transitions, eg. Index 1-3 denotes the
transition 2s(2)2p(4)3PE(J=2) -- 2s(2)2p(4)3PE(J=0).
The effective collision strengths for each transition are presented in
rows for a number of electron temperatures ranging from log10(T)=3.0
to log10(T)=7.0 in steps of 0.1dex.
