69GA c 1992Be57: {+69}Ge was produced in the Zn(|a,2n) reaction with
69GA2c E(|a)=36 MeV from the U-150 cyclotron at the Nuclear Physics Institute
69GA3c Uzbekistan Academy of Sciences. The electron capture decay of {+69}Ge
69GA4c and the daughter nuclues properties were studied. Measured K-capture
69GA5c probabilities for |b transitions to 574, 872, and 1106-keV levels.
69GA c 1976Ho09: {+69}Ge produced by bombarding {+66}Zn with 19 MeV |a
69GA2c particles from the Heavy Ion Accelerator at Yale University via the
69GA3c {+69}Ge(|a,n) reaction. Gammas were detected with Ge(Li) and NaI
69GA4c detectors. Measured E|g, I|g and |g|g(|q) for |q(|g)=90|'-180|'
69GA c 1975Pa22: {+69}Ge was produced in the {+69}Ga(p,n) reaction with
69GA2c E(p)=7 MeV. Gammas were detected with Ge(Li)-NaI(Tl) detector system.
69GA3c Measured |g|g(|q) for |q(|g)=92|'-246|'
69GA c 1970Dz05: {+69}Ge was produced by bombarding 40 MeV {+12}C ions that
69GA2c was produced at the accelerator of the Nuclear Reaction Laboratory at
69GA3c JINR on a cobalt target. Four Ge sources were then prepared by
69GA4c chemical methods. The decay was studied by using a double toroidal
69GA5c |b spectrometer to measure the conversion-electron spectra.
69GA6c |a(exp) measured from Ice and Ice/I|g(872). The conversion-electron
69GA7c spectrum was normalized to |a{-total}(872) by the use of a mixed source
69GA8c {+69}Ge and {+137}Cs and measuring the ratio I{-(K+L+M)872}/I{-(K)662}
69GA9c and I|g(662)/I|g(872)
69GA c 1969Kh10:{+69}Ge was produced by bombarding Ga with 18-MeV protons from
69GA2c the cylcotron at the Nuclear Physics Institute, Uzbekistan Academy of
69GA3c Sciences. Gammas were detected with stilbene crystals scintillators.
69GA4c Level lifetimes measurements were performed by |b|g and |g|g delayed
69GA5c coincidences, |g|g(|q) for |q(|g)=90|'-270|'.
69GA c 1969Zo01: {+69}Ge was produced by bombarding Ga{-2}O{-3} targets with
69GA2c 13 MeV deuterons from the MIT cyclotron, which was followed by chemical
69GA3c separation. Gammas were detected with Ge(Li) and NaI detectors.
69GA4c Measured E|g, I|g, |g|g coincidences, and {+69}Ge T{-1/2}.
69GA c 1963Sc27: {+69}Ge was produced by bombarding natural gallium oxide with
69GA2c deuterons from the Indiana University cyclotron. Gammas were detected
69GA3c with a NaI crystal. Measured E|g, I|g, E|b+, I|b{++} and |g|g and
69GA2c |b{++}|g coincidences.
69GA c 1951Hu38: {+69}Ge source was produced via the {+69}Ga(d,2n) reaction
69GA2c with the 11.5 MeV deuterons from the Indiana University cyclotron.
69GA3c The decays were studied using a magnetic spectrograph. Measured |g,
69GA4c I|g, E|b+, I|b{++}, |b{++}|g coincidences and {+69}Ge T{-1/2},
69GA2c |g-ray measurements from photoelectrons of Pb and U radiators,

69GA cG RI(D)$On the basis of |g|g, 1969Zo01 suggest placing part of I|g
69GA2cG (1723|g) with the 2044 level; however, a comparison with I|g
69GA3cG (1723|g)/ I|g(1404|g) from (p,|g) and (n,n'|g) suggests that all
