65CO c Adapted from the XUNDL dataset for 2009Pa16 compiled by by B. Karamy
65CO2c and B. Singh (McMaster), also including some data received from D.
65CO3c Pauwels in an email reply to B. Singh on May 12, 2009; and the XUNDL
65CO4c dataset for 2019Ol02 compiled by E.A. McCutchan (NNDC,BNL) on
65CO5c December 20, 2020
65CO c 2019Ol02: {+65}Fe source was from the decay of {+65}Mn produced by
65CO2c {+238}U(p,F) with 1.4 MeV proton from the pulsed CERN Proton
65CO3c Synchrotron Booster on an UC{-x} target. Fission products thermally
65CO4c released from the target were ionized by the ISOLDE Resonance
65CO5c Ionization Laser Ion Source (RILIS), mass separated and implanted on a
65CO6c thin aluminum foil surrounded by a fast plastic scintillator for
65CO7c detecting |b particles and two truncated-cone shaped LaBr{-3}(Ce)
65CO8c crystals and two HPGe detectors for detecting |g rays. Measured E|g,
65CO9c I|g, |b|g|g-coin, |b|g(t), |b|g|g(t). Deduced levels, J, |p, T{-1/2},
65COac |b-decay branching ratios, log {Ift}. Comparisons with shell-model
65CObc calculations with the LNPS interaction. Even though a saturated mixed
65COcc source of {+65}Fe g.s. and isomer was used, the decay scheme of {+65}Fe
65COdc g.s. |b decay can be constructed based on |g|g-coin gating on 883|g and
65COec |g singles which are only seen in the decay of {+65}Fe ground state.
65CO c 2009Pa16: {+65}Fe source was produced by {+238}U(p,F) with 30 MeV
65CO2c proton from the LISOL facility of the Cyclotron Research Center (CRC)
65CO3c at Louvain-La-Neuve (Belgium) on a 10 mg/cm{+2} {+238}U target inside
65CO4c a gas catcher for stopping and thermalizing the recoiling fission
65CO5c products. Ions leaving the gas are transported through a SextuPole Ion
65CO6c Guide (SPIG), accelerated, mass separated, and implanted into a
65CO7c detection tape surrounded by three thin plastic |DE detectors for
65CO8c detecting |b particles and two MINIBALL clusters for detecting |g rays.
65CO9c Measured E|g, I|g, |b|g|g-coin, |g(t). Deduced levels, J, |p,
65COac parent T{-1/2}, |b-decay branching ratios, log {Ift}. 2009Pa16 also
65CObc study {+65}Fe decay using {+65}Fe source produced in deep inelastic
65COcc reaction {+238}U({+64}Ni,X|g) with E=430 {+64}Ni beam at ANL and
65COdc measuring |b|g|g|g-coin.
65CO c 2005GaZR (thesis): {+65}Fe source is from the decay of {+65}Mn produced
65CO2c by fragmentation of a 61.8 MeV/nucleon {+76}Ge beam on a {+58}Ni target
65CO3c at GANIL. Measured E|g, I|g. Deduced levels, J, |p, decay branching
65CO4c ratios, log {Ift}. Report 7 transitions.
65CO c The decay scheme is considered incomplete by the evaluator due to
65CO2c possible missing levels in a large energy gap of about 5.5 MeV between
65CO3c the highest observed level at E=2470 keV and Q-value=7967 keV {I6},
65CO4c mainly because of possible unobserved |g rays from those levels.
65CO cB IB$From |g+ce intensity balance at each level. All |b feedings should
65CO2cB be considered as upper limits and thus associated log| {Ift} values as
65CO3cB lower limits, due to possible missing |g rays in this incomplete decay
65CO4cB scheme. Original values from 2019Ol02 and 2009Pa16 deduced in the
65CO5cB same way by the authors are given under comments.
65CO cG E,RI$From 2019Ol02, unless otherwise noted. Values reported in 2009Pa16
65CO2cG are from the measurement using {+65}Fe source from {+238}U(p,F); values
65CO3cG from the decay of {+65}Fe source produced in deep inelastic reaction
65CO4cG {+238}U({+64}Ni,X|g) in 2009Pa16 are given under comments as noted
65CO5cG where available and these values were communicated to B. Singh in an

65CO cN NR$0.613 {I31} from |S[%I(|g+ce to g.s.)]=100. Due to possible missing
65CO2cN unobserved transitions to g.s. in this incomplete decay scheme, this
65CO3cN value should be considered as an upper limit. 2019Ol02 use intensity
65CO4cN balance of entire A=65 decay chain to determine that |b feeding to
65CO5cN ground state is <0.3%. 2009Pa16 give a normalization factor of 0.20
65CO6cN {I6}, which the evaluator could not reproduce from the level scheme
65CO7cN given by 2009Pa16.
