✦ Synopsis

The differential He(p,p)He reaction cross-section was determined at a laboratory angle of 165°for proton energies between 1.6 and 3.6 MeV. A new method for preparation of helium-titanium (Ti) targets by direct current (DC) magnetron sputtering was employed for the first time. The currently measured cross-section data are compared with the available literature values. They show a similarly trend in the higher energy range but with a maximum difference of up to 12% in the absolute value. The uncertainty in the present cross-section data is about 7.3%.
