## Classical Trajectories of the Continuum States of the $$\cal{PT}$$ symmetric Scarf II potential

Anjana Sinha

We apply the factorization technique developed by Kuru et. al. [Ann. Phys. {\bf 323} (2008) 413] to obtain the exact analytical classical trajectories and momenta of the continuum states of the non Hermitian but $$\cal{PT}$$ symmetric Scarf II potential. In particular, we observe that the strange behaviour of the quantum version at the spectral singularity has an interesting classical analogue.
