TiO2 thin films with different Zn contents were successfully deposited by combining plasmas produced by laser ablation and magnetron sputtering in a hybrid configuration. The titania films were produced by ablating a TiO2 target keeping the ablation

In spite of the existence of a large quantity of experimental results for X-ray production cross sections by proton beam impact, recent publications emphasize the need for more measurements in several targets and energy ranges. Following these recomm

New measurements of the total crosssections of charged-current interactions of muonneutrinos and antineutrinos on isoscalar nuclei have been performed. Data were recorded in an exposure of the CHARM detector in an 160 GeV narrow-band beam. The antine
