Query: Orbital symmetry of a triplet pairing in a heavy Fermion superconductor
  UPt_3   The orbital symmetry of the superconducting order parameter in UPt_3 is
identified by evaluating the directionally dependent thermalconductivity and
ultrasound attenuation in the clean limit and compared with the existing data
for both basal plane and the c-axis of a hexagonal crystal. The resulting two
component orbital part expressed by (\lambda_x(k), \lambda_y(k)) is combined
with the previously determined triplet spin part, leading to clean limit and
compared with the existing data for both basal plane and the c-axis of a
hexagonal crystal. The resulting two component orbital part expressed by
(\lambda_x(k), \lambda_y(k)) is combined with the previously determined triplet
spin part, leading to the order parameter of either the non-unitary bipolar
state of the form: d(k) = b \lambda_x(k) + i j \lambda_y(k) or the unitary
planar state of the form: d(k) = b \lambda_x(k) + j \lambda_y(k) where b \perp
j = c, or a with the hexagonal unit vectors a, b and c. The d vector is
rotatable in the plane spanned by a and c perpendicular to b under weak applied
c-axis field because of the weak spin orbit coupling. Experiments are proposed
to distinguish between the equally possible these states.
