can be convoluted with $
{\rm (data)} \rightarrow S$ fitting to give an overall ${\rm (data)} \rightarrow V$ algorithm. This provides a new and efficient data analysis tool which in many cases obviates the need for independent ${\rm (data)} \rightarrow S$ inversion. Important advantages follow when fitting data for many energies since the underlying potential model guarantees that the energy dependence of the $S$-matrix will be smooth without the need to postulate parameterized forms for $S(E)$. Indeed, we have shown [@prl58] that ${\rm (data)} \rightarrow V$ inversion can provide a powerful alternative method for phase shift fitting of multi-energy scattering data for light nuclei.

Ref. [@prl] contained a restricted analysis of low energy $\vec{\rm d}$ + $^4$He data. A future paper will present a much more exhaustive analysis of the very large collection of data for this system. At a later stage we hope to present an analysis of $^6\vec{\rm Li} + ^4$He data, including tensor analysing powers.

The scattering of spin-1 nuclei from spin-0 targets

Formalism for spin-1 scattering
-------------------------------

In order to establish our notation, we outline the standard formalism for the elastic scattering of spin-1 projectiles from a spin-0 target in the presence of tensor forces.
