Because particles with different spin states interact, lithium atoms from opposite clouds should bounce off each other. (newscientist.com)
In explanation, the scientists note that the tubes» open ends facilitated the diffusion of lithium atoms into their interiors. (scientificamerican.com)
By strategically placing laser beams between a source of gaseous lithium atoms cooled to just 500 nano - degrees above absolute zero, and a reservoir that they could drain into, they created a cigar - shaped channel between the two. (newscientist.com)
