M054100100015 COMMENT The results of measurements from the threshold to 28 M054100100016 MeV of total photoneutron cross sections for natural M054100100017 cobalt, nickel, copper and gallium are given. M054100100018 The targets of the natural elements were exposed to M054100100019 the g-ray beam of the 31 MeV betatron of the Centro M054100100020 Studi Fisico-Biologici of Turin University. The M054100100021 photoneutrons were detected by means of 4PI M054100100022 thermalized neutron counter. For the four elements M054100100023 the integrated cross sections in mb*MeV are: Co - M054100100024 657 (89), Ni - 313 (48), Cu - 733 (105), Ga - M054100100025 947 (98).
