The branching ratio between the beta(-) and beta(+)/epsilon decay of (74)As has been measured in different host materials such as Ta, Al, Ge and mylar. No significant dependence of the branching ratio on the host material has been observed. The half-life of (74)As has also been measured in metallic Ta and in semiconductor Ge, no difference has been found and the results are in agreement with the literature value. The obtained results provide an upper limit for the possible host material dependence of the decay rate in (74)As. Copyright (c) EPLA, 2008.
