The antisymmetrised two-electron functions are constructed for the point
group Th, i.e. the symmetry group of unconventional superconductor PrOs4Sb14., and its subgroup D2h.The nodal structure of these
function depending on the wavevector group is investigated. Theoretical nodal
structure of these functions made possible to explain the experimental nodal
structure PrOs4Sb14. as a result of time-reversal symmetry violation.Comment: 10 page
