AbstractAbstract
[en] The 400 kV accelerator at Muenster has been optimized with respect to high energy resolution and stability. Yield curves of narrow resonances in 21Ne(p, γ)22Na have been investigated utilizing a windowless gas target of monolayer thickness (or less). The thermal Doppler broadening was the major contribution to the width of thin-target yield curves and was reduced by cooling the 21Ne target gas to temperatures as low as 25 K. Atomic effects on the shape of thin- and thick-target yield curves are discussed. (orig.)
