Summary
Pellets of sintered YBa2Cu3O7−δ with three different oxygen contents have been irradiated with fast neutron beams of energies 6.5, 3.3 and 4.4 MeV at fluences of 7.7·104, 1.3·105 and 1.4·109 n/cm2, respectively. The radiation damage has been investigated by comparing the critical temperature (T midc ), the zero resistivity and the onset temperature before and after neutron irradiation. The critical current has been measured for a few samples in the same experimental conditions. In all transport measurements two different responses to the neutron radiation are observed and discussed.
