Query: Thermal bremsstrahlung probing the nuclear liquid-gas phase transition   We present the results of the analysis of the hard photon production in the
$^{129}${Xe}+$^{\rm nat}${Sn} at 50{\it A} MeV system studied in the GANIL E300
experiment. The energy and angular hard photon distributions confirm the
existence of a thermal component which follows the recently measured thermal
bremsstrahlung systematics. Exploiting the performances of our complete
detection system, consisting of TAPS and 3 charged particle multidetectors, we
have also measured the hard photon multiplicity as a function of the charged
particle multiplicity.
