Abstract :
We report on global fits of optical-model parameters to 90 data points for View the MathML source X-rays and 17 data points of radiochemical data put together. By doing separate fits to the two kinds of data it is possible to determine phenomenologically the radial region where the absorption of antiprotons takes place and to obtain neutron densities which represent the average behaviour over the periodic table. A finite-range attractive and absorptive View the MathML source–nuclear isoscalar potential fits the data well. Self-consistent dynamical calculations within the RMF model demonstrate that the polarization of the nucleus by the atomic antiproton is negligible.
