The occurrence of QP excitations due to the Doppler-shift effect was detected regardless of the field direction in C ( H ) of the present clean sample, which is in sharp contrast to a previous report. Furthermore, the polar-angle-dependent C (θ) measured under a rotating magnetic field within the ac plane exhibits a shoulder-like anomaly at θ ∼ 45° and a sharp dip at θ = 90° ( H || a ) in the moderate-field region. These features are supported by theoretical analyses based on microscopic calculations assuming the gap symmetry of
