Figure 1

Dashed line is provided as a guide to the eye to indicate the shift in ℓ. For −20ℓ rod, only a portion of 1.0 ≤ ℓ ≤ 2.0 is presented to emphasise the shift in the rod minimum. The small peak observed at ~0 1 1.3 and ~−2 0 1.3 originated from the polycrystalline Ta clip of the sample holder.
