APAKAH MAKSUD LAMB SHIFT dalam CORSICA?
Pergelaran Lamb
Dalam fizik, pergeseran Lamb, yang dinamai oleh Willis Lamb, adalah perbezaan kecil dalam tenaga antara dua peringkat tenaga 2S1 / 2 dan 2P1 / 2 atom hidrogen dalam elektrodinamika kuantum. Menurut persamaan Dirac, orbit 2S1 / 2 dan 2P1 / 2 sepatutnya mempunyai tenaga yang sama. Walau bagaimanapun, interaksi antara elektron dan vakum menyebabkan pergeseran tenaga kecil yang berbeza untuk menyatakan 2S1 / 2 dan 2P1 / 2. Lamb dan Robert Retherford mengukur pergeseran ini pada tahun 1947, dan pengukuran ini memberikan rangsangan untuk teori renormalization untuk mengatasi perbezaan. Ia adalah penghasil elektrodinamika kuantum moden yang dibangunkan oleh Julian Schwinger, Richard Feynman, Ernst Stueckelberg dan Sin-Itiro Tomonaga. Domba memenangi Hadiah Nobel dalam Fizik pada tahun 1955 untuk penemuannya yang berkaitan dengan pergeseran Lamb.

Actually they differ by the ground-state Lamb shift plus small, well-measured QED
and fine-structure corrections to the excited-state energies. Thus an accurate
comparison of the two intervals allows one to determine the IS Lamb shift.

Because of this nonuniformity of the electric field, the tidal force on this shaking
electron is greatest when the electron is near the nucleus so that s-states (which
have nonzero probability of being found atr = 0) suffer the greatest Lamb shift.
