65NI c Adapted from the XUNDL dataset for 2009Pa16 compiled by by B. Karamy
65NI2c and B. Singh (McMaster) on May 12, 2009
65NI c 2009Pa16: {+65}Co source was produced by {+238}U(p,F) with 30 MeV
65NI2c protons from the LISOL facility of the Cyclotron Research Center (CRC)
65NI3c at Louvain-La-Neuve (Belgium) on a 10 mg/cm{+2} {+238}U target inside
65NI4c a gas catcher for stopping and thermalizing the recoiling fission
65NI5c products. Ions leaving the gas are transported through a SextuPole Ion
65NI6c Guide (SPIG), accelerated, mass separated, and implanted into a
65NI7c detection tape surrounded by three thin plastic |DE detectors for
65NI8c detecting |b particles and two MINIBALL clusters for detecting |g rays.
65NI9c Measured E|g, I|g, |b|g|g-coin, |g(t). Deduced levels, J, |p,
65NIac parent T{-1/2}, |b-decay branching ratios, log {Ift}.
65NI c 1988Bo06: {+65}Co source was produced via {+nat}W({+76}Ge,X) reaction
65NI2c with E=11.5 MeV/nucleon {+76}Ge primary beam from the UNILAC
65NI3c accelerator on a 36 mg/cm{+2} natural tungsten target. Reaction
65NI4c products were mass separated by the GSI online mass separator and
65NI5c collected at individual tape-transport stations. |b particles were
65NI6c detected with a 4|p lucite detector and |g rays were detected with
65NI7c two Ge detectors. Measured E|g, I|g, |b|g-coin, |b|g|g-coin. Deduced
65NI8c levels, J, |p, parent T{-1/2}, |b-decay branching ratios, log {Ift}.
65NI c 1985Ru05: {+65}Co source was produced via W({+82}Se,X) with E=11.5
65NI2c MeV/nucleon {+82}Se beam from the UNILAC accelerator on a 46 mg/cm{+2}
65NI3c natural tungsten target at GSI. Fragments were separated with the GSI
65NI4c on-line mass separator and transported to a measuring position inside a
65NI5c 4|p plastic |b-detector between two opposite Ge detectors. Measured
65NIIc E|g, I|g, |b|g-coin, |g|g-coin. Deduced parent T{-1/2}. Report two
65NI7c transitions and no decay scheme.
65NI c The decay scheme is considered incomplete by the evaluator due to
65NI2c possible missing levels in a large energy gap of about 4.7 MeV between
65NI3c the highest observed level at E=1274 keV and Q-value=5940.6 keV {I21},
65NI4c mainly because of possible unobserved |g transitions from those levels.
65NI cB IB$From |g+ce intensity balance at each level for excited levels. All
65NI2cB |b feedings should be considered as upper limits and thus associated
65NI3cB log| {Ift} values as lower limits, due to possible missing |g rays in
65NI4cB this incomplete decay scheme. Original values from 2009Pa16 deduced in
65NI5cB the same way by the authors are given under comments.
65NI cG $The following transitions assigned to {+65}Ni by 1988Bo06 have
65NI2cG been confirmed by later studies to belong to {+65}Co: 340.0 {I3},
65NI3cG 882.6 {I5}
65NI cG E$From 2009Pa16, unless otherwise noted
65NI cG RI,TI$Values quoted from 2009Pa16 are from weighted average of values
65NI2cG from decay of {+65}Co directly from the production (data set II) and
65NI3cG decay of {+65}Co from {+65}Fe decay (data set I; reported relative to
65NI4cG I|g=100 for 882.5|g in {+65}Co and re-normalized by the evaluator to
65NI5cG I|g=100 for 1141.1|g). Values quoted from 1988Bo06 are renormalization
65NI6cG of original values reported relative to I|g=100 for 310.6|g.

65NI cB IB$deduced by 2009Pa16 by comparing the off-resonant subtracted |b
65NI2cB activity with the total |g activity. Note that due to possible
65NI3cB unobserved missing transitions from possible missing levels in this
65NI4cB incomplete decay scheme, this value is considered as an upper
65NI5cB limit. Others: 91 (1988Bo06), >97 (1985Ru05)
65NI dB IB$No details are given in 1985Ru05 for how %I|b>97 is deduced.
65NI2dB 1988Bo06 deduce %I|b=91 from comparison of |b-singles and |b-coincident
65NI3dB |g-rays.
65NI cB LOGFT$even though this value is considered as an lower limit due to
65NI2cB I|b as an upper limit, this decay branch is considered as allowed
65NI3cB because of the strong feeding.
65NI L 63.18 23 1/2- 68.6 US 35 M
65NI cL $The reported |b feeding of %I|b<1.5 (2009Pa16) and |?0 (1988Bo06),
65NI2cL and a small negative value of -0.8 from |g+ce intensity imbalance
65NI3cL support the non-existence of a |b decay branch to this level.
