(In English) The existence of a resonance in the hyneron-pion system leads to a possibility of determining the SIGMA - LAMBDA relative parity and the ratio alpha /sub LAMBDA // alpha /sub 0/ of asymmetry coefficients alpha / sub i/sub L/ (in LAMBDA p + pi /sup -/) and alpha /sub 0/ (in SIGMA /sup +/ - p + pi /sup 0/). A proposal is made whic h allows the determination of these quantities by measuring only the up/down asymmetries of pions coming from LAMBDA and SIGMA decays. Various aspects of this proposal are discussed. The possible existence of other resonances is also emphasized. In particular it is shown that the existence of a resonance in the isotopic spin state I = 1 leads to some predictions concerning the existence of another resonance, probably in the I = 2 state.
