We present a quantum-statistical theory using the Kubo formalism to describe both CIP (current in plane) and CPP (current perpendicular to the plane) giant magnetoresistance (GMR) of thin magnetic sandwiches. It is shown that GMR for both geometries oscillates with the thicknesses of the sandwich's
Gamma ray spectra in the energy range of βΌ4-25 MeV were measured in the reaction 28 Si + 124 Sn at E( 28 Si) βΌ 150 MeV in coincidence with low energy Ξ³ -multiplicities. The spectra were analysed using a simulated Monte Carlo CASCADE code. The centroid energy and width of the giant dipole resonance w
