194HG c 2003Su30: {+194}Tl source was obtained as daughter of {+194}Pb isotope
194HG2c produced in the reaction of {+181}Ta({+19}F,6n) with 110 MeV {+19}F
194HG3c beam from BARC-TIFR Pelletron accelerator at Mumbai. |g rays were
194HG4c detected with two HPGe detectors. Measured E|g, I|g, |g|g-coin, |g(t).
194HG5c Deduced levels, parent T{-1/2}, absolute |g-ray intensities. Absolute
194HG6c |g-ray intensity measured from {+194}Pb-{+194}Tl successive decays and
194HG7c using absolute |g-ray intensity information for {+194}Pb decay
194HG c 1972Am03: {+194}Tl ions were obtained from spallation of lead by
194HG2c bombarding a PbF{-2} target with 660 MeV proton beam from the
194HG3c synchrocyclotron of the Nuclear Problems Laboratory of JINR. |g rays
194HG4c were detected with Ge(Li) detectors and conversion electrons were
194HG5c detected with a |b spectrometer with a Si(Li) detector (FWHM=3.2 keV at
194HG6c |?200 keV). Measured E|g, I|g, E(ce), I(ce). Deduced levels, J, |p,
194HG7c |e-decay branching ratios, log| {Ift}, conversion coefficients, |g-ray
194HG8c multipolarities.
194HG c Others: 1970To14, 1968Pe13, 1960Ju01, 1976WeZM
194HG c Due to a large gap (>3 MeV) between Q-value=5246 {I14} and the highest
194HG2c observed level of 2052, the decay scheme is considered incomplete and
194HG3c the branching ratios and Log {Ift} values are considered as
194HG4c approximated values.
194HG cE $E(|b{++})=4.4 MeV {I3}, reported by 1976WeZM probably
194HG2cE corresponds to a |b{++} transition to g.s.
194HG cE TI$From |g+ce intensity balance at each level
194HG cG $Several unplaced |g rays are given with the decay of the
194HG2cG 32.8-min isomer of {+194}Tl. These belong to either or both the
194HG3cG isomers. See |g rays from {+194}Tl |e decay (32.8 min)
194HG cG E,RI$From 2003Su30. Corresponding values from 1972Am03
194HG2cG are in agreement but less precise. The |g-ray intensities are
194HG3cG absolute intensities (per 100 decays of 33.0 min{+194}Tl)
194HG cG E(A),RI(A)$From 2003Su30 only
194HG cG M,MR$From ce data (1972Am03,1968Pe13) given under comments where
194HG2cG available. Uncertainty of 30% in ce data from 1972Am03 is assumed by
194HG3cG evaluators when deducing |d value
194HG cL $A 1292 level proposed on the basis of energy sums of
194HG2cL 219.0|g and 227.98|g (1972Am03) is discarded by the evaluator. The
194HG3cL 227.98|g is placed with an 8- level at 2138 known from (HI,xn|g) and
194HG4cL the 219.0|g is considered unplaced due to the absence of any other
194HG5cL supporting argument
194HG cL $Negative result in the search for super-deformation at
194HG2cL low-spin states populated by {+194}Tl |e decay. Expected 3600|g in
194HG3cL coincidence with 428|g (from 428 level) was not observed
194HG4cL (1989HeYZ, 1990HeYY).

194HG cE TI$as stated in 2003Su30, the branching ratio to g.s. appears to be
194HG2cE over-estimated, which could be due to errors on the branching
194HG3cE intensities of other levels or unobserved transitions to g.s.
