Nuclear polarized7Li and14N ions via ion beam surface interaction at grazing incidence

“…Therefore we scanned the wavelength of the spectrometer across the line under study and recorded the intensity of light of positive and negative helicity as indicated in Fig. 3 This result is consistent with a simulation which is based on the stable configurations of 14N as listed in Table 1 with estimated relative populations from beam-foil data [8] and transfer coefficients F u for N reflections. We deduce from Table 1 which is in agreement with earlier findings [2,3,6].…”

“…In this relation a rather simple and direct approach would be the use of an IBSIGI-target as a stripper in a tandem-accelerator for directly producing nuclear spin anisotropy during the acceleration process for applications in nuclear physics. As already pointed out in a previous publication [8] about one half of the nuclear orientation stems from…”

“…the quarter-wave plate was rotated in steps of 90 ~ with an angle of odd multiples of 45 ~ between the fast axis of the quarter wave plate and the polarizer axis [1,2,5,7,8]. Since the counting rates were low a proper background correction is important.…”
