Die Polarisation der Neutronen aus der Reaktion13C(α,n)16O

The angular distribution of the polarization of neutrons from the reaction¹³C(α,n)¹⁶O has been determined between 1.38 and 2.26 MeV energy of the α-particles by left-right asymmetry induced by elastic scattering from⁴He. The neutrons were detected by a time-of-flight method between a helium gas scintillation counter and two plastic scintillation counters. From Simon and Welton theory analysis a set of spectroscopic data has been obtained for seven states of the compound nucleus¹⁷O.
