abstract = {Experimental techniques involving epithermal neutrons can
be used to study the kinetic energies of the atoms that make
up the sample material. From the point of view of Nuclear
Engineering, this is the range of energies that is
necessarily traversed in the moderation process. From the
point of view of applied physics, it is an essential range
for the design of neutron sources associated with compact
accelerators. It is also worth mentioning that experimental
access to this energy range is a distinctive feature of
accelerator-based sources as opposed to reactor-based
sources. The atoms that compose the matter perform motions
characterised by a kinetic energy, determined not only by
the temperature of the medium, but also by interactions
resulting in vibrational modes. We can thus define a
parameter that we call effective temperature, linked to this
effect. The knowledge of the densities of the vibrational
states allows its evaluation, so that spectroscopic
techniques aimed at its measurement allow an indirect
assessment of it. Yet, there are techniques that allow
direct experimental access to these quantities which are
Deep Inelastic Neutron Scattering (DINS) and Neutron
Transmission (NT). The VESUVIO spectrometer (ISIS, UK)
allows both techniques to be performed simultaneously in the
same experiment. Although ISIS is a large neutron source,
such experiments were previously carried out at the defunct
LINAC in Bariloche (Argentina), making these techniques
affordable for small sources. In this work we show this
capability through combined DINS and transmission
experiments in a molecular liquid. We also discuss different
prospects for future use, extending the possibilities to
other techniques.},
