Abstract Using a set of explicitly correlated trial wavefunctions that describe the three lowest singlet and triplet states of the helium atom with symmetry S, P, and D, we calculate the decay rates for all possible magnetic quadrupole (M2) transitions: m 3 P 2 →n 1 S 0 , m 1 P 1 →n 3 S 1 , m 3 D 3 →n 1 P 1 , and m 1 D 2 →n 3 P 2 . Our values are in excellent agreement with the best results in the literature. © 2010 Wiley Periodicals, Inc. Int J Quantum Chem, 2011
