decay studies for all nuclides in A=222 mass chain (Z=84 to 92). A new nuclide (222Po) has since been observed.

In addition, new measurements have been reported in Rn, Th and Ra nuclides. The results obtained from various

theoret ical studies are g iven as comments . The updated level and decay schemes, and experimental decay and

reaction data on which they are based, are summarized and presented for all the nuclides with mass number A=

222. The adopted values o f level energies , leve l spins and par i t ies are g iven, and γ–ray energies , intensi t ies ,

as wel l as other nuclear properties are presented. The references, Jπ arguments, and necessary comments are

given in the text. All Q values have been adopted from 2011AuZZ. Theoretical work of 2009Mo27 was consulted.

See 2010Ch19 for 222Po isotope discovery and its mass measurements in the fragmentation of 238U beam at 670

MeV/nucleon with a 4g/cm2 9Be target fol lowed by separation by Fragment Recoil Separator facil ity at GSI.

Fragments were then injected into the cooler electron storage ring ESR. The mass and half–li fe was measured by

t ime–resolved Schottky Mass spectrometry technique. For the measurements of isotopic distributions of the

cross–sections, see 2010Al24.

Q(β–)=4430 SY ; S(n)=4090 SY ; Q(α )=5040 SY 2003Au03,2011AuZZ.

Estimated: ΔQ(β–)=300, ΔS(n)=360, ΔQ(α )=200 (2003Au03,2011AuZZ).

The nucleus was produced by 1989Bu09 in 232Th (600–MeV p) by spallation with a negative ion source where chemically

pure beams of halogen elements were produced; the products were mass separated. The measured half–lives provided

the information for the definite nuclear assignment of the products.

The calculations of 1973Ta30 by using the β–gross theory yielded T1/2≈100 s for the β decay half–li fe of 222At;

1984Kl06 calculated this half–li fe as 21.5 s by using a microscopic theory. 2010Li02 measured mass values using

Schottky mass spectrometry.

See 2010Al24 for measurement of production cross–section using cold–fragmentation at relativistic energies.

Estimated ΔS(p)=200 (2003Au03,2011AuZZ).

Potential energy and equilibrium deformations were calculated by 1994Li05, 1988So08, 1984Na22, 1983Ro14, 1982Le19,

1981Gy03. The nuclear binding energies were calculated and incipiency of deformation in this region is discussed

in 1986Ch23.

See 1983Ro14 for calculations of static quadrupole and hexadecapole moments.

2010Li02 measures mass values using Schottky mass spectrometry.

See 2009Qi07, 2004Re22 for predictions of cluster decay and its half–li fe. See 1989De11 for discussions on octupole

deformation and E1 transitions.

See 1987Ro08 for calculation of single–particle states and dipole moments as a function of octupole deformation, and

for B(E1)/B(E2) values at the equilibrium octupole deformation.

Higher order of deformations were considered by 1995De13; the level energies of the 2+, 4+ states in the g.s. band

and the 1–,3– states in the octupole–vibrational band were calculated. See 1995De13 for calculations, discussions

and comparison with experiments. See 1998Ra05 for calculations of level energies. Others: 2001Za04, 2001Za09. See

2003Ga34 for calculations of ground state properties.

222Rn Levels

The Kπ=0+ g.s. band and the Kπ=0– band at 600.66 keV have been interpreted as octupole parity–doublet bands. This

nucleus falls in the middle of the region of octupole deformation defined by the spin systematics for octupole

shapes (1990Ja11).

‡ From 226Th α decay and 222Fr β– decay. The uncertainties of γ ' s deexciting the levels above 1 MeV have been increased because

of a poor energy f it to the level scheme; therefore, the Eγ values have been rounded off here. See 222Fr β– decay section for

the experimental values l isted by the authors.

222Fr ββββ– Decay 1992Ru01

Parent 222Fr: E=0.0; Jπ=2–; T1/2=14.2 min 3 ; Q(g.s. )=2032 21 ; %β– decay=100.

222Fr–%β– decay: Relative photon intensities were normalized by 1992Ru01 to Iγ (324.2γ from 222Ra)=2.77 8 per 100

222Ra decays. This value was measured absolutely by 1969Pe17, and it has been adopted by the evaluator. However,

1992Ru01 did not provide their measured Iγ (324γ ) relative to the Iγ ' s given here. From the γ–transition

intensities shown on the decay scheme of 1992Ru01, Iγ normalization=0.49 6 ; an assumption of any β feeding to the

g.s . to be negligible yields Iγ normalization=0.51 6 ; by requiring that the log f1ut for a β feeding to the g.s.

is >8.5, Iβ is calculated to be <7%. Iβ (g.s . )=3% 3 yields Iγ normalization=0.50 6 .

The 222Fr β– decay scheme is presented as constructed by 1992Ru01 based on their β–gated γγ–coincidence

measurements. The decay scheme was built upon the previously known levels which were established up to the

1170–keV level .

β– radiations

See 1975We23 for singles β spectrum measurements. The spectrum shows a f lat tail of low intensity and extended to

much higher energy than the main portion of the data. After subtraction of this tail (which was assumed due to α

particles from 222Ra), an F–K analysis gives Eβ (max)=1780 20 for the endpoint which does not agree with the Eβ–

(to 111.12 level) .

† The energies of α ' s to the g.s. and to the 111–keV level are given as recommended by 1991Ry01 from Eα measurements of 1956As38

decreased 0.4 keV and 6.1 keV, respectively, by 1991Ry01 because of changes in calibration energies. All other Eα ' s are

calculated by the evaluator from Eα (g.s . ) and E(level) .

‡ Deduced from level scheme, except for Iα (to g.s. ) and Iα (to 111 level) , as indicated.

Parent 226U: E=0.0; Jπ=0+; T1/2=0.35 s 15 ; Q(g.s. )=7715 14 ; %α decay=100.

T1/2(226U)=0.20 s 5 was measured by 1990An22,0.5 s 2 by 1973Vi10, 0.281 s 9 by 2000He17, 0.260 s 20 by 2001Ku07,

0.260 s 10 by 1999Gr28.

See 2009Ni06, 2009Ro06, 2008Sa40, 2007Pe30, for calculations of alpha decay half–lives.

%α (226U)=100 is adopted in 1996Ak02. From the gross β– decay calculations of 1973Ta30, the ε decay branch is

estimated to be %ε<0.05.

1997Mo25 calculated the partial half–li fe of 226U β+ decay as >100 s.

deduced from HF(α to g.s. from 222U)=1.0 by using Q(α ) (222U)=9500 100 , Iα (to g.s. )=80% 20
