 57CR c  2003Ma02: {+57}V obtained from fragmentation of the primary beam of
 57CR2c  {+86}Kr{+14++} at E=140 MeV/nucleon in a thick Be target followed by
 57CR3c  separation of fragment isotopes based on atomic mass and atomic number.
 57CR4c  Measured E|g, I|g, |g|g, |b|g using six Ge detectors from the NSCL
 57CR5c  SeGA array
 57CR c  Placement of |g rays is from energy sums, no |b|g|g coincidence events
 57CR2c  were detected in 2003Ma02
 57CR c  1998So03: {+57}V activity produced by the fragmentation of 64.5
 57CR2c  MeV/nucleon {+65}Cu beam impinging on a {+9}Be target and subsequent
 57CR3c  mass separation using the lise3 spectrometer. Measured T{-1/2} from
 57CR4c  |b{+-} singles and |b-|g coincidence decay curves. Three |g rays
 57CR5c  were detected at 267 {I4}, 700 {I50} and 900 {I50} keV with
 57CR6c  intensities of 60, 30, and 30%, QRPA calculations
 57CR c  1998Am04: T{-1/2} measurement and production of {+57}V
 57CR c  1990Tu01: {+57}V production
 57CR cB IB,LOGFT$ Apparent |b feedings, thus log {Ift} values should be
 57CR2cB considered (by the evaluator) as lower limits only, thus no
 57CR3cB uncertainties in log {Ift} values are listed
 57CR cG RI$I|g/100 decays were deduced (by 2003Ma02) from the number of
 57CR2cG observed |g rays, the |g-ray efficiency curve and the number of
 57CR3cG {+57}V implants correlated with |b decays
 57CR cG E(A)$ In {+14}C({+48}Ca,|an|g), a 1581 level was shown to decay by
 57CR2cG 639.1|g and 1313.8|g. In |b{+-} decay,

 57CR CL E$ it should be noted that 1314.3 5+267.8 3=1582.1 6 and
 57CR2CL 892.5 6+692.4 4=1584.9 7 differ by 2.8 9 KEV. This
 57CR3CL suggest two separate levels near this energy. See
 57CR4CL comment in 'adopted levels', where 892.5|g and 1314.3|g
 57CR5CL are placed from two separate levels based on above discrepancy
 57CR6CL in energy sum and on results from 14C(48CA,ANG) reaction.
 57CR7CL In the latter reaction, a strong 639.1|g is also seen from a 1581
 57CR8CL level. It is not obvious why this |g ray was missed in |b{+-} study
