57V H TYP=FUL$AUT=BALRAJ SINGH$CUT=12-APR-2010$CIT=ENSDF$
57V c 2005Li53: {+57}Ti isotope produced in fragmentation of {+86}Kr{+34+}
57V 2c beam on a {+9}Be target. Secondary fragments were selected using the
57V 3c A1900 fragment separator. Fragment identification was performed by a
57V 4c combination of multiple energy-loss signals and time of flight method.
57V 5c Measured E|g, I|g, |g|g, |g|b(t), lifetime with 12 Ge detectors from
57V 6c the MSU segmented Ge array and double-sided Si microstrip detector.
57V cB IB$ deduced by the evaluator from |g-ray intensity balances and the
57V 2cB ground state feeding deduced by 2005Li53 from the total number of
57V 3cB {+57}Ti nuclei implanted in the Double-sided Si microstrip detector
57V 4cB (DSSD). The listed |b feedings should be treated as apparent values
57V cB LOGFT$ All values are considered as lower limits.
57V cL E$ from least-squares fit to E|g's
57TI P 0.0 (5/2-) 98 MS 5 10.64E3 51
57TI cP T$ Deduced from fit of the fragment-|b-decay curve considering the
57TI2cP exponential decay of the parent, exponential growth, and decay of the
57TI3cP daughter {+57}V, and a linear background term. The value obtained
57TI4cP was compared with that obtained from fragment-|b-|g decay curves for
57TI5cP each of the transitions assigned to {+57}Ti (2005Li43). See adopted
57TI6cP levels of {+57}Ti for previous half-life measurements
57TI cP J$ From {+57}Ti adopted levels
57TI cP QP$ from 2009AuZZ, 2003Au03.
