Resumen en inglés

The $\gamma$ -decay branching ratios of $^{49}$V have been studied in the $\beta$ /EC decay of $^{49}$Cr. The $\gamma$-ray spectrum has been measured with a 70% relative efficiency co-axial germanium detector calibrated in efficiency with a precision of about 0.5%. The primary result is the measurement of the relative branching ratios of the three main $\gamma$ rays in the decay of $^{49}$Cr. Large discrepancies were found with a previous experimental work. The $^{49}$Cr sample was produced by proton impact on a ZrO$_{2}$ target and collected at the ISOLDE facility of CERN and enabled us to re-evaluate the decay scheme of $^{49}$Cr. The new data allow the use of this nucleus for future high-precision calibration work.< Leer menos
