|Abstract:||The first ever search for 2ε and εβ+ decay of 174Hf was realized using a high-pure sample of hafnium (with mass 179.8 g) and the ultra low-background HPGe-detector system located 225 m underground. After 75 days of data taking no indication of the double beta decay transitions could be detected but lower limits for the half-lives of the different channels and modes of the decays were set on the level of limT1/2 ∼ 10E16 − 10E18 a.|
