Abstract:
The energy levels, observed spectral lines, and transition
probabilities of the neutral vanadium atom, V I, have been compiled.
Also included are values for some forbidden lines that may be of
interest to the astrophysical community. Experimental Lande g-factors
and leading percentage compositions for the levels are included where
available, as well as wavelengths calculated from the energy levels
(Ritz wavelengths). Wavelengths are reported for 3985 transitions, and
549 energy levels are determined. The observed relative intensities
normalized to a common scale are provided.

Note (1): The level energies are quoted from Thorne+ (2011ApJS..192...11T 2011ApJS..192...11T),
except for five levels with "SCa" in the Notes column. Those five
levels are from Sugar & Corliss (1985aeli.book.....S 1985aeli.book.....S), and their
energy was adjusted in this work using our level optimization with
the LOPT code of Kramida (2011CoPhC.182..419K 2011CoPhC.182..419K). All Lande g-factors
are quoted from Sugar and Corliss (1985) (see text in section 3).
Ionization energy is an adjusted value from James+
(1994JChPh.101.4485J 1994JChPh.101.4485J) (see section 5).
Note (2): The given uncertainty approximately corresponds to the minimum
uncertainty of separation from other levels connected to the given
one by observed transitions. Uncertainty of excitation energy from
the ground level can be estimated by combining the given value in
quadrature with the uncertainty of the ground level, 0.002cm-1.
Note (3): Number of identified lines in Table 2 from which the level value
was derived.
Note (4): Configuration and term of the leading component of the eigenvector,
except when the second or third components are used in cases when it
is necessary to preserve the uniqueness of the designation of the
level. The additional numbers appearing in designations of parent
terms of 3d3 and 3d4 configurations are the indexes of
Nielson & Koster (1963) as implemented in Cowan's codes. Strongly
mixed levels are designated with the integer part of their energy in
cm-1 (for odd levels, followed by the parity symbol).
Note (5): Configuration and term of the second leading component of the
eigenvector, except when the first component is used in cases when
it is necessary to preserve the uniqueness of the designation of
the level.
Note (6): Quoted from the previous compilation of Sugar & Corliss 1985,
(Atomic Energy Levels of the Iron-Period Elements: Potassium through
Nickel (Washington, DC: ACS), 1985aeli.book.....S 1985aeli.book.....S).
Note (7): Definition of notes as follows:
QI = Questionable interpretation: configuration and term labels and/or
eigenvector composition may be inadequate;
LD = Lande factor has been discarded because the J value was revised;
SCa = Sugar & Corliss (1985aeli.book.....S 1985aeli.book.....S), adjusted in this work.
