The branching ratio between the β- and β+/ ε decays of 74As has been measured in Ge and Ta environments at temperatures ranging from 250 mK to 300 K. No significant dependence on the temperature has been found. Our work confirms the results of the low-temperature measurement of Kumar et al (2008 Phys. Rev. C 77 051304), but with increased precision due to the special choice of the radioactive source.
