HIGH-SPIN G-FACTORS IN DY-154

g-factors of excited states in 154Dy were measured up to high spins. A method that combines the recoil-distance technique with the use of th e large transient magnetic fields was applied. The measurement was sen sitive only to states which were populated almost-equal-to 13.5 ps aft er the nuclear reaction. Hence the influence of unobserved quasi-conti nuum feeding states on the measured precession angles was minimized. T he results are compared with calculated g-factors. They can be explain ed by the neutron i13/2 alignment in the positive- and negative-parity sequences at medium spins. They also confirm the predicted alignment of protons in the band termination region of spins I greater-than-or-e qual-to 30 HBAR.
