Using a set of explicitly correlated trial wave functions that describe the three lowest singlet and triplet states of the helium atom with symmetry S, P, and D, we calculate the electric quadrupole oscillator strengths for all possible 1 S‐ 1 D, 1 P‐ 1 P, 1 D‐ 1 D, 3 S‐ 3 D, 3 P‐ 3 P, and 3 D‐ 3 D transitions and compare their accuracy to our earlier calculations of the electric dipole oscillator strengths. © 2008 Wiley Periodicals, Inc.
