General Comments:

Identification: genetic relationship of product from neutrons on 170Er to known γ rays from 167Ho (1960Wi10, 1974Ka21); coincidences between Ho x rays and γ rays attributed to 170Er(n,α) (1977Tu01).

The level scheme is from 1999As03.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔS(p)=300 (1995Au04).

E(level): From Eγ.

Jπ(level): Values for the 1/2[521] band are based on consistency of band parameters with those for 1/2[521] bands in neighboring n=101 isotones.

E(γ): From 167Tb β- decay.
