  Angular distribution of the final particles in the decay $\Lambda_c^+\to K^-
\, \Delta (1232)^{++} \to K^- \, p \, \pi^+$ of the polarized charmed baryon is
discussed. Asymmetries are proposed which allow for determination of the
components of the $\Lambda_c^+$ polarization vector. The precession angle of
the polarization in the process of baryon channeling in a bent crystal is
directly related to these asymmetries. The decay rate and asymmetry parameter
for the $\Lambda_c^+\to K^- \, \Delta (1232)^{++}$ decay are calculated in the
pole model and compared with experiment.
