spin echo technique

[′spin ¦ek·ō tek‚nēk]
(nuclear physics)
A variation of the nuclear magnetic resonance technique in which the radio frequency field is applied in two pulses, separated by a time interval t, and a strong nuclear induction signal is observed at a time t after the second pulse.

By coupling the experimental helium spin echo technique with advanced first-principles calculations, we were able to study the dynamic behaviour of a cyclopentendienyl layer on a copper surface, and to deduce that the charge transfer between the metal and the organic molecule was occurring in a counter-intuitive sense," Dr Holly Hedgeland, of the Department of Physics at the University of Cambridge, one of the co-authors of the paper reporting the research, explained.
