  We have previously investigated joint $\Lambda \bar{\Lambda}$ decay in the
reaction $e^+ e^- \rightarrow \gamma \Lambda(\rightarrow p\pi^-)
\bar{\Lambda}(\rightarrow \bar{p}\pi^+)$. The cross-section-distribution
functions encountered were relativistically covariant and expressed in terms of
scalar products of the four-momentum vectors of the particles involved. In the
present, sequel investigation, we show that by working with three-momentum
scalars instead results could possibly become more transparant.
