We have correlated a sample of 99 Seyfert 1 & 98 Seyfert 2 (Rafanelli et al., 1995) interacting galaxies with the survey and pointed ROSAT data and have detected 91 Seyferts 1 & 47 Seyfert 2s in the X-ray band. We have performed spectral and timing analysis of the X-ray detected sources, and we have examined the relation of the X-ray luminosity L X with the interaction strength Q.

The neutron capture gamma-ray technique was used for the analysis of Cu-Ni alloys, widely used in industry. The two elements, which are very close in atomic number, have widely separated characteristic capture gamma quanta. A sensitivity of 7x10 counts per unit thermal neutron flounce per 1% change in Ni/Cu ratio was obtained. Samples of any shape can be analyzed without a need for any special ...
