0.0	(3-)	26.4 ms 2 % α = 100	Calculated %ε+%β⁺=5×10^-4, from gross β-decay strength function (1973Ta30).
0.0+X	J		Bandhead of high spin structure reported 1991Sc19. E(level): Bandhead of high spin structure reported 1991Sc19. Band based on 0⁺x level, with parity unknown. Note that. The authors of 1991Sc19 suggest that Jπ of level at x keV is relatively high, and thus this level is not the g.s. of ²²⁰Ac (x\|=0). This suggestion is based on the observation that the difference between the highest and lowest observed states is only 18 spin units, whereas much higher spins have been reached with this reaction in other nuclei. Also the γ rays seen in ²²⁴Pa α decay were not seen in this study.

E(level)	E(gamma)	Comments
28.00	28.0	E(γ): Possible doublet. See details in ²²⁴Pa α decay M(γ): E1 is assumed by the evaluators based on intensity balance in ²²⁴Pa α decay, considering that either M1 or E2 would give a very large α(total) value and thus a large I(γ+ce)(28γ) indicating a strong decay to 28-keV level which is inconsistent with observation in 1996Li05
40.69	40.7	M(γ): Reported as M1 in 1996Li05. Evaluators adopted M1⁺E2 for transition-intensity balance purposes.
