The O125901100007 practical threshold lies here also about 8 MeV above O125901100008 the theoretical limit. The reaction cross section, O125901100009 obtained by taking into account the abundance of 110-PdO125901100010 in nat-Pd (11.72%) reaches a maximum in the O125901100011 neighbourhood of 37-38 MeV with a maximal value 62.5 mbO125901100012 HISTORY (20081205A).Zero was added after decimal points in O125901100013 Data-lines.
