${{\boldsymbol \Lambda}}$ DECAY PARAMETERS

See the ``Note on Baryon Decay Parameters'' in the neutron Listings. Some early results have been omitted.

$\alpha _{0}$ $/$ $\alpha _{−}$ = $\alpha\mathrm {( {{\boldsymbol \Lambda}} \rightarrow {{\boldsymbol n}} {{\boldsymbol \pi}^{0}} )}$ $/$ $\alpha\mathrm {( {{\boldsymbol \Lambda}} \rightarrow {{\boldsymbol p}} {{\boldsymbol \pi}^{-}} )}$ INSPIRE search
