Abstract
Energy levels in 160Er and 159Er were excited in the reactions 28Si( 136Xe, 4n) 160Er and 28Si( 136Xe, 5n) 159Er, and the product nuclei, recoiling with a velocity v = 0.07 c were stopped in a plunger instrument after traversing a volume of hydrogen gas. The angular distribution of de-excitation γ-rays was studied as a function of flight time and gas pressure. Appreciable perturbations were detected in 160Er at times as short as 2 ps and in an angular momentum region as high as 12ħ. No perturbation could be detected in the 21 2 + level of 159Er even after 12 ps, signifying a low value for the g-factor of this level.
