| Zusammenfassung | Resonances of the (p,γ)-type with 13C- and Al-targets, together with the 13C(p,n)13N-threshold reaction, were used to determine the magnet factor k for the analysing magnet, which relates the particle energy with the frequency of the NMR probe. A non-constant energy-to-frequency relationship was found for low magnetic fields. Using the known energy dependence of k, an energy uncertainty of ± 1.2 keV for a proton beam of an energy of 2 MeV can be achieved, provided the procedure for the adjustment of the magnetic field of the analyser is followed. |
