Ammonia adsorption studies of Li(11)BD4 and Mg((11)BD4)2
On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
