General Comments:

1960Wi10, 1974Ka21: identification through genetic relationship of product from neutrons on 170Er to known γ rays from 167Ho.

1977Tu01: coincidences between Ho x rays and γ rays attributed to 170Er(n,α)

2019No05: theory: calculated neutron and proton pairing residual interaction strength, binding energy, and moments of inertia using self-consistent Hartree-Fock plus BCS framework, with self-consistent blocking and Skyrme SIII parametrization.

2015Ch53: calculated odd-even mass differences, binding energy per nucleon, pairing energy using RMF+SLAP and RMF+BCS methods.

The level scheme is tentative according to 1999As03
