Archivio Istituzionale della RicercaPellets of sintered YBa 2Cu 3O 7-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 7.7·10 4, 1.3·10 5 and 1.4·10 9 n/cm 2, respectively. The radiation damage has been investigated by comparing the critical temperature (T c mid ), 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.

Abstract
Pellets of sintered YBa 2Cu 3O 7-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 7.7·10 4, 1.3·10 5 and 1.4·10 9 n/cm 2, respectively. The radiation damage has been investigated by comparing the critical temperature (T c mid ), 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.
