Abstract.
The \(\gamma\)-decay branching ratios of 49V have been studied in the \(\beta\)/EC decay of 49Cr. 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 49Cr. Large discrepancies were found with a previous experimental work. The 49Cr sample was produced by proton impact on a ZrO2 target and collected at the ISOLDE facility of CERN and enabled us to re-evaluate the decay scheme of 49Cr. The new data allow the use of this nucleus for future high-precision calibration work.
