A fairly recent paper --
"Deformed space–time transformations in Mercury"
International Journal of Modern Physics B - March 2017
Abstract at URL - http://www.worldscientific.com…10.1142/S0217979217501685
-- claims detecting transmutations in a mole of Mg exposed to ultrasound
-- without gamma emission
In previous papers by the authors conjecture ultrasound cavitation initiates piezo-nuclear reactions.

These experiments do not seem difficult or expensive to replicate.
The equipment and materials appear readily available.
Does anyone know whether these results have been replicated? - or rebutted?
