Nuclear Cooling Temperatures Below

As a technique for measuring nuclear moments and investigating nuclear level structure, low temperature nuclear orientation has long been kept from areas of current activity in low energy nuclear physics by the half life limitation caused by needs of sample preparation and cooling to below 1 K. 

At this stage no nuclear composite objects can be formed yet, since they would instantly disintegrate in collisions with hard electromagnetic quanta. The stabiK2ation occurs for temperatures below 0.1 MeV. Primordial synthesis of light nuclei took place at that cooling stage of the Universe (O Sect. 12.3). 

If the fat is cooled to some point below the melting point of the highest melting component and allowed to fully equilibrate (crystalhze to the maximum extent in the most stable polymorph), there will be some ratio of sohd to liquid fat dependent on the nature of the TAG mixture in the natural fat. This solid fat content (SFC) is often measured by a pulsed nuclear magnetic resonance (NMR) technique. A plot of the maximum amount of fat crystallized (SFC) at sequentially higher temperatures...
