Q(β-)=-1.45×104 keV SYS(n)= 1.36×104 keV SYS(p)= 1.8×103 keV SYQ(α)= 3.8×103 keV SY
Reference: 2012WA38

References:
  A  145Tm p decay (3.1 μs) 

General Comments:

Produced by 90Zr(197Au,x), E=30 MeV/nucleon (2000So11). Identification using A1200 mass separator at Michigan State University. 144Er is also observed in the proton decay of 145Tm (2003Ka04), populating the ground state and the first 2+ level.

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

Q-value: ΔS(n)=718, ΔS(p)=566, ΔQ(α)=643 (2003Au02)

  330  330E(γ): This γ-ray was not observed, its existence is deduced from the energy difference between the two proton peaks in the decay of 145Tm
