Abstract: The aim of this work was to perform a systematic study of the hydrogen influence on the superconductivity of the non-transitionelements Be, Zn, Cd, In, Sn, Tl and Pb. For hydrogen is almost insoluable in these metals it was introduced into the host lattices by ion implantation at low temperatures. In all cases the critical temperature could be enhanced. In comparison the implantation of deuterium also lead to an improved superconductivity. The observed isotope effects are not understood. By implantation of He those effects onthe critical temperature were measured, which occur by radiation damage caused by H(D) implantation. The critical temperatures achieved in these experiments were always significantly smaller than those caused by H and D respectively. By an application of McMillan's theory it was possible to show that a phononic origin of the hydrogen effect can explain the experimental results.
