General Comments:

1985Ho01: 144Nd(3He,t), E=12.398 MeV 15 studied IAS, total width=45 keV 7, escape width=8.0 keV 14, spreading width=52 keV 5, p-escape probability=17.8% 19.

There are 2 high-spin data sets, 1993Gl03 and 1994ZhZW. Their main discrepancy is the decay from the 3349 keV state, where the 221 keV + 459 keV sequence in 1993Gl03 is reversed in 1994ZhZW.

Q-value: Note: Current evaluation has used the following Q record 550.5 25 6526.7 15 4703.0 22 849 7 1995Au04

E(level): From least square fit to levels where γ information is available; if ΔEγ was unknown, a value of 1 keV was used.

Jπ(level): Assignments for levels below 600 keV are based upon expected configuration=((ν 2f7/2)+(π 2d5/2)+(π 1g7/2)); while coupling with (π,2d3/2) (π,1h11/2) orbitals are expected at higher energies.
