摘要：

The simultaneous measurement of the spatial coordinates and times of psBAR annihilating at rest in a H-2 target at very low density rho (rho/rho0 < 10(-2), rho0 being the STP density) gives the possibility of evaluating the behavior of the pBAR stopping power in H-2 at low energies (below 120 keV). It is different from that of protons (the Barkas effect). Moreover, it is shown that a rise at low-energy values ( less than or similar to 1 keV) is needed to agree with experimental data.
