The Existence of Electronic Glasses, Na-ND3 and NaCa-ND3.

In this application we request 2 days of rapid access time on SANDALS or NIMROD to demonstrate the existence of amorphous metal-amine solutions, the Ogg glasses.Results from this proposal are the key objective in our Leverhulme grant (RPG-2018-094). A proposal was entered to the ILL in the last round, but despite the science case being supported, the experiment was not awarded beamtime. Our previous attempt at ISIS was unsuccessful due to quenching into too high temperatures (100K), which we now know from our magnetometric measurements is not sufficient to yield the Ogg state. Due to the reactive, cryogenic, air-sensitive nature of the sample, DSC and similar measurements are not possible. Neutrons are desperately required!
