  In the recent years, the hydrofluoroolefine HFO1234ze(E) (C3H2F4) has been
subject to a growing interest for refrigerant applications. This novel gas is
also considered a promising alternative in gaseous particle detectors and
gaseous voltage insulation devices, thanks to its low global warming potential.
In this contribution, measurements of electron transport coefficients and
reaction rates in C3H2F4 are analyzed by an iterative procedure. A complete set
of scattering cross sections for electrons in C3H2F4 has been obtained and
validated by a systematic comparison of electron swarm parameters with
experimental measurements in pure C3H2F4 as well as in gas mixtures of
C3H2F4/CO2. Since the electron attachment of C3H2F4 is strongly influenced by
the gas density, accurate calculations of the critical electric field strength
in such mixtures are also reported in this paper.
