    "abstract": "Assuming a~simple spherical relativistic mean field model of the nucleus, we\nestimate the width of the antiproton--neutron annihilation ($\\Gamma_n$) and the\nwidth of antiproton--proton ($\\Gamma_p$) annihilation, in an antiprotonic atom\nsystem. This allows us to determine the halo factor $f$, which is then\ndiscussed in the context of experimental data obtained in measurements recently\ndone on LEAR utility at CERN. Another quantity which characterizes the\ndeviation of the average nuclear densities ratio from the corresponding ratio\nof the homogeneous densities is introduced too. It was shown that it is also a\ngood indicator of the neutron halo. The results are compared to experimental\ndata as well as to the data of the simple liquid droplet model of the nuclear\ndensities. The single particle structure of the nuclear density tail is\ndiscusssed also.",
