57CR 57V B- DECAY (350 MS) 2003MA02 ENSDF 201004
57CR H TYP=FUL$AUT=BALRAJ SINGH$CUT=12-APR-2010$CIT=ENSDF$
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
