General Comments:

Other reaction: 150Nd(30Si,6nγ), E=178 MeV. Measured γγ coin. Detector: 8 π array of 20 hyperpure germanium detectors. Measured γ rays from high-spin members of rotational bands, as well as strong γ rays from a quasicontinuum spectrum (1996Cr07).

Spin assignments are based on rotational structure and angular correlation data of 1978Dr04 in 162Dy(16O,4nγ). Additional specific arguments are given for individual levels.

E(level): From 162Dy(16O,4nγ) (1978Dr04).

Jπ(level): Jπ assignments are based on rotational structure, and on γ-ray multipolarities and decay patterns. Specific arguments are given with individual levels.

T1/2(level): From recoil distance technique in 159Tb(19F,4nγ) (1987Ga14), unless otherwise specified.

M(γ): From γ(θ), and RUL for transitions with a known half-life, and DCO (directional correlation from oriented nuclei).
