Stark Broadening Parameters for Isolated Neutral Atom Lines
Electron impact widths, shifts, and ion broadenings parameters for isolated neutral atom lines
This table lists electron impact widths and shifts (in Å) according to Section II.3ca* and ion broadening parameters (beta) according to Eqs. (224) and (457), all for a nominal electron density N=1016cm-3. Electron impact widths and shifts are linear in N as long as the lines are indeed isolated and there is no Debye shielding, A scales as N1/4, and B is independent of N but proportional to T. Also given are the relative values (WA) of the widths calculated from the adiabatic approximation as given by Eq. (263) expressed in percentage of the widths calculated here, the percentage contributions (WS) of "strong" collisions and (WQ) of quadrupole interactions, and the percentage errors (DR) in the shifts due to the omission of some perturbing levels.
Stark Broadening Parameters for Isolated Lines from Singly Charged Ions
Electron impact widths and shifts of isolated lines from singly charged ions
This table lists electron impact width and shifts (in Å) of isolated (see table for neutral atom) lines from singly charged ions at an electron density N=1017 cm-3 calculated  according to Section II.3d. Also given are the percentage contributions to the width of strong collisions (WS), quadrupole interactions (WQ), and collisions (WC) for which the characteristic function B(d, x) had to be replaced rather arbitrarily by 3pi/2 to avoid a serious overestimate of width and shift contributions from strong collisions. (DS is the percentage contribution of strong collisions to the shift.) Other quantities are the ratio (kT/E) of thermal energies (at kT=104K) and characteristic level separations, the relative angular momenta (L) of electrons making (almost) strong collisions and the effective Gaunt factor (G) calculated from the present widths and Eq. (459). Finally, DS/S is a measure of the failure in the fulfillment of sum rules for the squares of dipole matrix elements, S here being the sum of the squares of these matrix elements. The lines are characterized by their
wavelength, running number of Wiese et al  or , multiplet number of Moore  or , principal and orbital quantum numbers of the optical electron in the two states, and multiplicity and total orbital angular momentum quantum numbers of these states. (Wavelengths are averaged over the multiplets.)
