Abstract

Extremely large precession angles (0.24 rad) have been observed when Coulomb-excited, 2-MeV/A actinide recoils decelerate in ferromagnetic Gd. In both ${}^{232}{Th}$ and ${}^{238}U$ the $g$ factors increase above spin $I = 18 ℏ$ . This is the first direct evidence for rotation alignment of $i_{\frac{13}{2}}$ protons in the actinides. In ${}^{232}{Th}$ there is also evidence for alignment of $j_{\frac{15}{2}}$ neutrons below $I = 16 ℏ$ .
