  A study of the baryon excitation spectra provides a deep insight into the
inner structure of baryons. Most of the world-wide efforts have been directed
towards $N^*$ and $\Delta^*$ spectroscopy. Complementary data from double and
triple strange baryon spectra are lacking and foreseen to be obtained with the
PANDA experiment in the near future. Earlier Monte Carlo studies demonstrated
that with an expected cross section in the order of $\mu$b, PANDA will be able
to copiously observe the channel $\bar{p}p\rightarrow
\overline{\Xi}^+\Lambda\,K^-$, including the two resonances
$\Xi\left(1690\right)^-$ and $\Xi\left(1820\right)^-$, with a negligible
background contribution. In this study, the feasibility to determine the spin
and parity of the $\Xi\left(1690\right)^-$ and $\Xi\left(1820\right)^-$
resonances is investigated by making use of a partial wave analysis employing
the PAWIAN software. The presented results demonstrate the capability of the
PANDA experiment to determine the spin-parity of these resonances with a few
days of data taking.
