  Fusion cross-sections have been measured for the asymmetric system 16O+165Ho
at energies near and deep below the Coulomb barrier with an aim to investigate
the occurrence of fusion hindrance for the system. Fusion cross sections down
to ~ 700 nb have been measured using the off-beam gamma-ray technique. The
fusion cross sections have been compared with the coupled channel calculations.
Although the onset of fusion hindrance could not be observed experimentally, an
indication of a small deviation of the experimental fusion cross-sections with
respect to the calculated cross-sections could be observed at the lowest energy
measured. However, the energy onset of fusion hindrance has been obtained from
the extrapolation technique and is found to be about 2 MeV below the lowest
energy of the present measurement.
