List of levels for 151HO

E(level): From least-squares fit to Eγ’s. The 898γ from 1564 level was was omitted from the least-squares fitting procedure as it resulted in a poor fit with normalized χ²=7.5

J^π(level): For high-spin (J>11/2) levels, the assignments are mainly based on multipolarities of selected transitions (about 12 in all) from γ(θ), γ(lin pol) and intensity-balance arguments. The shell-model predictions are also used. Ascending spins are assumed as the excitation energy rises.
