From Steven Krivit
The article “Many happy returns for cold fusion” contained a subtle but significant ambiguity (28 March, p 10). The article mentions my scepticism of “cold fusion” as a theoretical explanation for the low-energy nuclear reaction experimental phenomena, but fails to mention other theoretical models for these phenomena which also propose nuclear processes, namely, neutron-catalysed weak interaction processes. According to several experts, at least one of these models appears to be a viable explanation.
