Abstract

The dynamic dipole polarizabilities for the four lowest triplet states (23S, 33S, 23P, and 33P) of helium are calculated using the B-spline configuration interaction method. Present values of the static dipole polarizabilities in the length, velocity, and acceleration gauges are in good agreement with the best Hylleraas results. Also the tune-out wavelengths in the range 400 nm-4.2 μm for the four lowest triplet states are identified, and the magic wavelengths in the range 460 nm-3.5 μm for the 23S→33S, 23S→23P, and 23S→33P transitions are determined. We show that the tune-out wavelength of 23S state is 413.03828(3) nm, which corroborates the value of Mitroy and Tang [Phys. Rev. A 88, 052515 (2013)PLRAAN1050-294710.1103/PhysRevA.88.052515], and the magic wavelength around 1066 nm for the 23S→33P transition can be expected for precision measurement to determine the ratio of transition matrix elements (23S→23P)/(33P→63S).
