  In a more general electroweak theory, there could be Higgs particles that are
odd under $CP$, and also Higgs-like particles which are not eigenstates of
$CP$. We discuss distributions which for the Bjorken process are sensitive to
the $CP$ parity. Correlations among momenta of the initial electron and
final-state fermions yield this kind of information. We discuss also
observables which may demonstrate presence of $CP$ violation and identify a
phase shift $\delta$ which is a measure of the strength of $CP$ violation in
the Higgs-vector-vector coupling, and which can be measured directly in the
decay distribution. We present Monte Carlo data on the expected efficiency, and
conclude that it is relatively easy to determine whether the produced particle
is even or odd under $CP$. However, observation of any $CP$ violation would
require a very large amount of data.
