62GA c 2021Or01: {+62}Ge isotope produced in {+9}Be({+78}Kr,X),E({+78}Kr)=345
62GA2c MeV/nucleon reaction at the RIBF-RIKEN facility. Fragments were
62GA3c separated, selected and identified in mass and charge by the BigRIPS
62GA4c separator according to B|r-|DE-tof, and transported and implanted into
62GA5c the WAS3ABi array consisting of three double-sided silicon-strip
62GA6c detectors (DSSSDs) at the exit of the ZeroDegree spectrometer. The |g
62GA7c rays were detected using the EURICA array of HPGe detectors. Measured
62GA8c E|g, I|g, implant-decay time correlations. Deduced parent levels, J|p,
62GA9c and Gamow-Teller strengths. See also 2023OrZZ.
62GA d 2017RuZX is superseded by 2021Or01
62GA c 2014Gr10: study of Gamow-Teller decay of T=1, J|p=0+ {+62}Ge g.s. to
62GA2c N=Z {+62}Ga nucleus. The {+62}Ge source was formed in fragmentation of
62GA3c 750 MeV/nucleon {+78}Kr beam impinging a {+9}Be target, followed by
62GA4c B|r-|DE-B|r and time-of-flight analysis by using FRS fragment separator
62GA5c and various scintillation and ionization detectors at GSI facility. The
62GA6c ions of {+62}Ga were implanted into a pack of six 1 mm thick
62GA7c double-sided silicon strip detectors (DSSSDs). Measured E|g, I|g,
62GA8c (particle)|g-coin, (fragment)|b- and |b|g-coin, half-life of {+62}Ge
62GA9c ground state. Deduced levels, J|p, |e feedings, log {Ift} values,
62GAAc B(GT) strengths. Comparison with shell model and QRPA calculations.
62GA cE TI$From 2021Or01, deduced from %I|g of the single transition to
62GA2cE g.s. from each level, unless otherwise noted.
62GA cG $1247.2-keV |g ray with I|g=2.1 {I+9-7} and 2413.9-keV |g ray with
62GA2cG I|g=1.8 {I+8-7} reported by 2014Gr10 are omitted as these have not
62GA3cG been seen in better statistics data in 2021Or01.
62GA cL $1247.2- and 2413.9-keV levels proposed by 2014Gr10 are omitted
62GA2cL as the respective ground-state transitions of 1247.2 keV and
62GA3cL 2413.9 keV have not been seen in better statistics experiment by
62GA4cL by 2021Or01.
62GA cG E,RI$From 2021Or01. Available values from 2014Gr10 are listed under
62GA2cG comments. Intensities are per 100 decays of {+62}Ge
62GA cL E$From |g-ray energies.
62GA cL J$As given in 2021Or01, based on allowed log| {Ift} values from 0+

62GA cE $B(F)=2.0 (2021Or01)
62GA cE $Value of log| {Ift}=3.525 {I34} probably suggests this |b transition
62GA2cE to be superallowed as it overlaps unweighted averaged log| {Ift}
62GA3cE of 3.485 {I1}, deduced from 15 precise (uncertainties of |<6.9)
62GA4cE {Ift} values of superallowed |b transitions listed in Table XVI
62GA5cE of 2020Ha30 evaluation. If Q(|e)=9730 {I140}, as suggested by 2021Or01
62GA6cE is used, then log| {Ift}=3.49 {I4}.
