Precise half-life measurements for $^{38}$Ca and $^{39}$Ca
The half-lives of Ca-38 and Ca-39 have been measured at ISOLDE of CERN. The REXTRAP facility was used to prepare ultra-clean samples of radioactive nuclei for precision decay spectroscopy. Ca-38 is one of the T-z = -1, 0(+). 0(+) beta-emitting nuclides used to determine the vector coupling constant...

| description | The half-lives of Ca-38 and Ca-39 have been measured at ISOLDE of CERN. The REXTRAP facility was used to prepare ultra-clean samples of radioactive nuclei for precision decay spectroscopy. Ca-38 is one of the T-z = -1, 0(+). 0(+) beta-emitting nuclides used to determine the vector coupling constant of the weak interaction and the V-ud quark-mixing matrix element. The result obtained, T-1/2 = 443.8(19) ms, is four times more precise than the average of previous measurements. For Ca-39, a half-life of T-1/2 = 860.7(10) ms is obtained, a result in agreement with the average value from the literature. |
