英文摘要	The dynamic dipole polarizabilities for the four lowest triplet states (2(3)S, 3(3)S, 2(3)P, and 3(3)P) 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 mu m for the four lowest triplet states are identified, and the magic wavelengths in the range 460 nm-3.5 mu m for the 2(3)S -> 3(3)S, 2(3)S -> 2(3)P, and 2(3)S -> 3(3)P transitions are determined. We show that the tune-out wavelength of 2(3)S state is 413.038 28(3) nm, which corroborates the value of Mitroy and Tang [Phys. Rev. A 88, 052515 (2013)], and the magic wavelength around 1066 nm for the 2(3)S -> 3(3)P transition can be expected for precision measurement to determine the ratio of transition matrix elements (2(3)S -> 2(3)P)/(3(3)P -> 6(3)S).
