We examine the superconducting gap nodes in crystals with tetrahedral (Th) symmetry. The (0, 0, 1) phase of the three-dimensional order parameter in the triplet channel has nodes in the [0 0 1] directions. Following a second order phase transition to the state (0, i | η2 |, | η1 |), each node lifts away from the Fermi surface and splits into two deep dips. We discuss this scenario in the context of multiple superconducting phases in PrOs4 Sb12. © 2006 Elsevier B.V. All rights reserved.
