The high momentum tail (HMT) of nucleons, as a signature of the short-range
correlations in nuclei, has been investigated by the high-energy bremsstrahlung
γ rays produced in 86Kr + 124Sn at 25 MeV/u. The energetic
photons are measured by a CsI(Tl) hodoscope mounted on the spectrometer CSHINE.
The energy spectrum above 30 MeV can be reproduced by the IBUU model
calculations incorporating the photon production channel from np process in
which the HMTs of nucleons is considered. A non-zero HMT ratio of about 15%
is favored by the data. The effect of the capture channel np→dγ is
demonstrated
