Q(β-)=-925 keV 23S(n)= 5.90×103 keV 5S(p)= 2939 keV 11Q(α)= 8348 keV 5
Reference: 2012WA38

References:
  A  224Pa α decay  B  209Bi(14C,3nγ)

General Comments:

Assignment: 208Pb(15N,3n) excit (1970Bo13); parent of 216Fr (1970Bo13,1987FuZT)

Calculations, compilations, systematics:

Alternating parity bands: 1993Sc11

Heavy-ion emission: 1985Po14

Level structure, odd-odd actinides: 1994So16

Spontaneous emission of heavy ions: 1986Po06

Other reactions:

2006Ho03: 209Bi(18O,3nαγ), E=90-94 MeV. Measured Eγ, Eα, αγ coin, γ(θ)

1999Bo52: 205Tl(22Ne,X), E<145 MeV.

Levels: Bands α and B, C and d, and E and F form three sets of alternating parity bands. The parities of these bands are not known, but bands α, C, and E are of the same parity whereas bands B, d, and F are of opposite parity.

Gammas: All γ-ray data are from 224Pa α decay (for levels seen in that decay) and from 209Bi(14C,3nγ) data set (for levels seen in that reaction)

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

Q-value: Q(β-)=-917 27, S(n)=5890 50, S(p)=2932 17, Q(α)=8348 4 (2003Au03).

E(level): From least squares fit to Eγ.

Jπ(level): For levels seen in 224Pa α decay: for possible Jπ assignments based on γ multipolarity, α HF, and shell model expectations, see 224Pa α decay data set (1996Li05). For levels at x keV and above: the assignments are from (14C,3nγ) data set (1991Sc19) and are based on γγ, γ multipolarity and band structure.

I(γ): Relative Iγ from level

     0.0+XJ   E(level): band A; PARITY=π. The authors 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.
