  Precision measurements of neutron decay offer complementary access to
particle physics at small distance scales or high energies. In particular they
allow tests of the V-A structure of the weak interaction. Among many
experimental activities which are ongoing around the world we present two new
experiments which are planned or studied for the near future. While the neutron
lifetime still bears significant experimental uncertainties and thus has to be
studied with greatest precision the two-body decay ($n\to H\bar\nu$) of the
neutron has not yet been observed. Despite its small branching fraction it
offers many possibilities in the framework of particle physics. Both cases are
addressed in this contribution.
