Beitrag zur Kernspektroskopie an36Cl,90Y und40K durch Messung der Polarisation von γ-Strahlung nach Neutroneneinfang
The circular polarization ofγ-rays following the capture of polarized thermal neutrons in nuclei was measured. The degree of polarization confirmed the spin 2+ for the 0.777 MeV level of90Y and the spin 0− or 3− for the 0.029 MeV level of40K. Further theE2/M1 mixing ratio of the 8.58 MeV decay to the ground state of36Cl was measured.
