Fine-structure intervals separating the 10H(L = 5), 10I(L = 6), 10K(L = 7), and 10L(L = 8) states of helium have been measured precisely, using a fast-beam microwave--laser resonance technique. The results: 10H-10I, 157.0508(26) MHz; 10I-10K, 60.8152(18) MHz; and 10K-10L, 27.1835(63) MHz agree well with theoretical predictions which include contributions due to ''retardation'' or ''Casimir'' forces.
