Query: Measurement of the Decay Asymmetry Parameters in $\Lambda_c^+ \to
  \Lambda\pi^+$ and $\Lambda_c^+ \to \Sigma^+\pi^0 $   We have measured the weak decay asymmetry parameters ($\aLC $) for two \LC\
decay modes. Our measurements are $\aLC = -0.94^{+0.21+0.12}_{-0.06-0.06} $ for
the decay mode $\Lambda_c^+ \to \Lambda\pi^+ $ and $\aLC = -0.45\pm 0.31 \pm
0.06$ for the decay mode $\Lambda_c \to \Sigma^+\pi^0 $. By combining these
measurements with the previously measured decay rates, we have extracted the
parity-violating and parity-conserving amplitudes. These amplitudes are used to
test models of nonleptonic charmed baryon decay.
