73GE c 1976Fo07: {+73}Ga source was produced from irradiation of natural Ge
73GE2c powder with neutrons provided by the neutron generator of the
73GE3c University of Helsinki and the betatron of the Department of
73GE4c Radiotherapy. |g rays were detected with Ge(Li) detectors. Measured
73GE5c E|g, I|g, |g|g-coin. Deduced levels, J, |p, |b-decay branchings,
73GE6c log {Ift}.
73GE c 1970Wa21: {+73}Ga source was produced via fast neutron (n,p) reaction
73GE2c on enriched {+73}Ge and (n,fission) reaction on {+232}Th and {+238}U
73GE3c with neutrons from the University of Arkansas 400-KV Cockcroft-Walton
73GE4c linear accelerator. |g rays were detected Ge(Li) and NaI(Tl) detectors
73GE5c and |b particles were detected with a cylindrical plastic detector.
73GE6c Measured E|g, I|g, E|b, I|b, |g|g-coin, |b|g-coin, |b(t). Deduced
73GE7c levels, J, |p, |b-decay branchings, parent T{-1/2}.
73GE c 1969Cl11: Measured E|g with Si(Li) detectors. No level scheme is given.

73GE cB IB$from 100-|S%I(|g+ce to 66.7+13.3+g.s. from levels above 66.7). A
73GE2cB value of 9 {I1} is deduced by 1970Wa21 from
73GE3cB 100-[%I|g(297.3|g)+%I|g(325.7|g)=91 {I1}] with the latter from
73GE4cB comparison of total I|b and I(|b|g) on the 295-328 keV |g region, but
73GE5cB this value does not exclude |g feedings to the 66.7 level and levels
73GE6cB below from levels above 392 level as well as |g feedings to 13.3 level
73GE7cB from 364 and 392 levels, since those |g rays are not observed in
73GE8cB 1970Wa21 but are observed in 1976Fo07.

73GE2cG to 66.7 level) relative to I(297|g)=100 and theoretical |a=8.4. A value
73GE3cG of 9.6 {I12} is from weighted average of 9.1 {I8} in 1970Wa21, 9 {I1}
73GE2cG in 1958Yt22 and 15 {I2} in 1959Ma04. Note that 1976Fo07 give a
73GE3cG discrepant value of 22 {I5}, which implies a 44% |b{+-} feeding to the
73GE4cG 67 level inconsistent with |b measurements (1970Wa21, 1958Yt22,
73GE5cG 1959Ma04). The average value from |b measurements, on the other hand,
73GE6cG gives a negative intensity balance.
