Abstract.

The results of an experimental search for spontaneous cluster decay in 127I 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 2410Ne, 2812Mg, 3012Mg, 3214Si, 3414Si, 4820Ca, 4921Sc cluster radioactivity in 127I have been achieved.
