  We present a study of the superconducting energy gap performed with point
contact spectroscopy in a single crystal of the superconductor Zr0:97V0:03B2.
We determined the size and evolution with temperature of the energy gap, the
transition temperature in the compound occurs at the onset of Tc = 9.3 K. The
point contact junctions were measured from 1.7 to 20 K. The differential
conductance as a function of bias voltage was analyzed with the
Blonder-Tinkham-Klapwijk model, the evolution of the gap with temperature was
compared with the BCS theory, the ratio 2{\Delta}(0)/KBTC was of the order of
8.95 indicative of a very strong coupling limit.
