摘要
The results of an experimental search for spontaneous cluster decay in I-127 are presented. Several possible channels have been investigated considering an exposure of 33834 kg . day collected by a large-mass highly radiopure NaI(Tl) set-up deep underground in the Gran Sasso National Laboratory of the INFN. New lower limits on the lifetime of Ne-24(10), Mg-28(12), Mg-30(12), Si-32(14), Si-34(14), Ca-48(20), Sc-49(21) cluster radioactivity in I-127 have been achieved.
