Inverse scattering from mixed data


We first consider the fixed-$l$ inverse scattering problem. We show that the zeros of the regular solution of the Schrödinger equation, $r_{n}(E)$, which are monotonic functions of the energy, determine a unique potential when the domain of energy is such that the $r_{n}(E)$'s range from zero to infinity. This suggests that the use of the mixed data of phase-shifts $\{\delta(l_0,k), k \geq k_0 \} \cup \{\delta(l,k_0), l \geq l_0 \}$, for which the zeros of the regular solution are monotonic in both domain and range from zero to infinity, offers the possibility of determining the potential in a unique way. This will be demonstrated in the JWKB approximation.
