129SN c 2004Ga24: The {+129}In isotope was obtained by thermal-neutron
129SN2c induced fission of a {+235}U carbide target inside the combined
129SN3c target and ion source ANUBIS. During the measurements of singles
129SN4c data, surface ionization was used to select the element In and
129SN5c thereby suppress the daughter activities.
129SN c Measured E|b, E|g, I|g, |g|g, |b|g(coin), |g|g(t), T{-1/2} (isotope)
129SN2c with 3 Ge detectors of which one was a LEPS. Three
129SN3c Ge detectors were also used for the Q{-|b} measurement, where the LEPS
129SN4c detector was used as a |b spectrometer.
129SN cB IB$From 2004Ga24
129SN CB IB(X)$Total feeding for 1762 and 1803 levels; but most of this
129SN2CB feeding is expected to be for 1803 level. The feeding for the
129SN3CB 1762 level is expected to be much weaker in view of first-
129SN4CB forbidden unique transition involved
129SN cG M$From Adopted Gammas
129SN CL E$From least-squares fit to E|g data
129SN CL E(A)$2004Ga24 notes that an imbalance of the |g-ray intensities for
129SN2CL transitions feeding and depopulating this level has been observed.
129SN3CL The authors indicate that unobserved |g feeding is most likely the
129SN4CL cause of the apparent |b feeding and that true |b feeding is assumed
129SN5CL to be zero for this level.
