Abstract

Mean lifetimes of the 4⁺ levels in the ground-state rotational bands of ¹⁵⁸Dy and ¹⁶⁴Er were measured. Both levels were excited through (p, 2n) reactions. The lifetime of the level in ¹⁵⁸Dy was measured using a recently developed multi-channel version of the microwave method. The measurement in ¹⁶⁴Er was carried out with the earlier version of the microwave technique. The results of these measurements are τ(¹⁵⁸Dy) = 108±12 ps, τ(¹⁶⁴Er) = 124±12 ps. The B(E2; 4⁺ → 2⁺) are compared with the corresponding B(E2; 2⁺ → 0⁺) values and found to be in agreement with the rotational model.
