Lamb-shift source [`lam ´shift ´sȯrs] NUCLEONICS A device for producing a beam of polarized ions from one-electron atoms in their 2s excited state; the 2s and 2p levels, initially separated by the Lamb shift, are mixed by magnetic and electric fields, and selected nuclear magnetic substrates are then depopulated, leaving the remaining atoms in a state with large nuclear polarization. |
