Query: Multiphoton ionization through the triplet states of Mg by linearly and
  circularly polarized laser pulses   We theoretically study multiphoton ionization through the triplet states of
Mg by linearly polarized (LP) and circularly polarized (CP) fs laser pulses.
After the construction of the atomic basis using the frozen-core Hartree-Fock
potential (FCHFP) as well as the model potential (MP) approaches for both
singlet and triplet series which show rather good agreements with the existing
data in terms of state energies and dipole matrix elements, we solve
time-dependent Schr\"{o}dinger equations with $3s3p$ $^{3}P_{1}$ as an initial
state, and calculate the total ionization yield and photoelectron energy
spectra (PES).
