Polarization of high spin nuclear levels via tilted multifoil interaction

It has been demonstrated that with suitably spaced carbon foils, tilted with respect to the particle momentum, a large polarization can be generated in high spin nuclei by the tilted foil atomic polarization. Two experiments have been carried out with such polarized high spin isomers: a measurement of the sign of the quadrupole moment of the 10⁺ isomer in⁵⁴Fe, and a new attempt of higher sensitivity at detecting a possible positive parity admixture to the 17/2^– isomer in⁹³Tc.On leave from the Hahn-Meitner Institut, Berlin, W.
