J 7224|a decay to a level in {+188}Bi which is connected via an M1 |g to the (10-) {+188}Bi isomer is probably unhindered (2006An04), implying J|p({+192}At; 0.0+x)=(9-,10-,11-); the lowest-energy {+192}At configurations are expected to result from coupling an s{-1/2}, f{-7/2} or (possibly) i{-13/2} proton to a p{-3/2} or i{-13/2} neutron and none of those multiplets includes an 11- state. Only the (|p 2f{-7/2})~#(|n 1i{-13/2}) configuration multiplet includes 9- or 10- states so 2006An04 favor this configuration assignment, consistent with presence of |p f{-7/2} isomers in {+191}At and {+193}At.

This level decays by an 7235-keV |a particle to the 187 keV {i9} 1/2{++} level in {+189}Bi (2003Ke08). Based on the properties of this transition, 2003Ke08 propose this level as the {+193}At g.s. In the {+189}Bi Adopted Levels, 1/2{++} state located at 184 keV 8 (2017Jo05). 
J Spin-parity assigned from 2003Ke08 on the basis of observed favored |a decay to the (1/2{++}) level in {+189}Bi, and subsequent favored |a transition to the 1/2{++} g.s. of {+185}Tl. For the underlying configuration 2003Ke08 suggest a |p(4p-1h) 1/2+ intruder state, originated by the promotion of an s{-1/2} proton across the Z=82 shell gap. This is similar to the case of the {+191}At ground state, which is also assigned J|p=(1/2+).

This level is proposed as the first excited state in {+193}At by 2003Ke08, based on the |a-decay properties to both the 7/2{+-} 100-keV level in {+189}Bi and the 9/2{+-} {+189}Bi g.s., as well as on the |a-|g coincidences 
Two |a branches deexcite this state to levels in {+189}Bi: a) E(|a)=7325 {i5} keV, I(|a)=98 {i2} %, HF=1.1 {i3}, to the (7/2{+-}) 100-keV level in {+189}Bi; b) E(|a)=7423 {i5} keV, I(|a)=2 {i2} %, HF=64 {i64}, to the {+189}Bi g.s. The hindrance factors imply an |DL=0 unhindered |a transition in the first case. Note that the quoted HF values are as given in 2003Ke08, based on their reinterpretation of the observed values, by assuming the existence of an unobserved |?34-keV |g ray connecting the {+193}At 13/2{++} isomeric state at 39 {i7} keV, with the 5-keV isomeric level. 
E The uncertainty in the excitation energy, obtained from |a-particle energy differences, is too great to establish the actual sequence of the 1/2{++} and 7/2{+-} levels. The adopted ordering is that suggested in 2003Ke08, with support from the |a-decay properties to levels in {+189}Bi, and the observed |a particle coincidences with the 100-keV |g ray in {+189}Bi (2003Ke08).

This level depopulates via a 7106 {i5} keV |a decay to the 13/2{++} 358-keV state in {+189}Bi. The hindrance factor calculated in 2003Ke08 for this transition, assuming an 100% |a branch, is 0.24 {i4}. To explain this anomalously low value of HF, 2003Ke08 propose that there exists an IT decay branch deexciting this state to the 7/2{+-} level, taking about 76 {i10} % of the decay strength, and thus leaving 24 {i10} % for the |a intensity. The unobserved |?34-keV IT branch would probably have an E3 character, consistent with the observed half-life for the level.

The authors also compare their half-lives with nine previous measurements in the literature, mostly imprecise values with an uncertainty larger than 50 ms, except for 253 ms {I9} in 1997Pu01 (Z.

T$from 1981Vo03. Other value: 2.4 min {i2} (1975Ra03). 
J$J from atomic beam laser spect (1985Co24). Parity assignment is based on the agreement between calculated |m (=+0.94 to +1.5) for a 1/2+,1/2[400] Nilsson state, and the measured value of +1.50 {i3} (1985Co24). This assignment is supported by the energy systematics of this Nilsson state in {+231}Ac and {+237}Pa, the g.s. in both nuclei. Although the calculated |m (=2.15 to 2.50) for a 1/2+,1/2[660] Nilsson state may also be consistent with the measured value, this assignment would be unlikely because of the large (|?6.7) theoretical decoupling constant for this band. Such a decoupling constant would cause the J=5/2 and 9/2 members of the band to lie below the J=1/2 state. Nevertheless, the g.s. of {+227}Fr is very likely mixed with other even-parity states through the Coriolis and |DN=2 interactions (1987Bo04). See 1986Ek02 for a detailed discussion of magnetic moments in this nucleus. A stable octupole deformation is preferred over a reflection-symmetric interpretation (1988Le13).

No fission fragments were detected (1992MeZV). An upper limit of 1|*10{+-4}% for |b-delayed SF decay branch was given by 1992MeZV. 
From Q(|a) systematics of 1985Wa02, Q(|a)({+234}Ra)<3 MeV. Therefore, {+234}Ra is expected to decay predominantly by |b to {+234}Ac.

$Only one correlated decay-chain event was observed with E|a(1)=7935 {I30} keV, |Dt(1)=29.1 ms; E|a(2)=7406 keV, |Dt(2)=85 ms and E|a(3)=6997 keV, |Dt(3)=2.08 s. Definite assignment is ambiguous, since: E|a(2) is consistent with E|a's of both, the {+201}Fr g.s.
