Measurement of astrophysical S factors and electron screening potentials for d(d, n){sup 3}He reaction In ZrD{sub 2}, TiD{sub 2}, D{sub 2}O, and CD{sub 2} targets in the ultralow energy region using plasma accelerators
Abstract
The paper is devoted to study electron screening effect influence on the rate of d(d, n){sup 3}He reaction in the ultralow deuteron collision energy range in the deuterated polyethylene (CD{sub 2}), frozen heavy water (D{sub 2}O) and deuterated metals (ZrD{sub 2} and TiD{sub 2}). The ZrD{sub 2} and TiD{sub 2} targets were fabricated via magnetron sputtering of titanium and zirconium in gas (deuterium) environment. The experiments have been carried out using high-current plasma pulsed accelerator with forming of inverse Z pinch (HCEIRAS, Russia) and pulsed Hall plasma accelerator (NPI at TPU, Russia). The detection of neutrons with energy of 2.5MeV from dd reaction was done with plastic scintillation spectrometers. As a result of the experiments the energy dependences of astrophysical S factor for the dd reaction in the deuteron collision energy range of 2-7 keV and the values of the electron screening potential U{sub e} of interacting deuterons have been measured for the indicated above target: U{sub e}(CD{sub 2}) Less-Than-Or-Slanted-Equal-To 40 eV; U{sub e}(D{sub 2}O) Less-Than-Or-Slanted-Equal-To 26 eV; U{sub e}(ZrD{sub 2}) = 157 {+-} 43 eV; U{sub e}(TiD{sub 2}) = 125{+-}34 eV. The value of astrophysical S factor, corresponding to the deuteron collision energy equal to zero, in the experimentsmore »
