Über eine Absorptionslinie des Jodatoms

Abstract: Bei 2062,1 A.-E. wird eine Absorptionslinie des Jodatoms gefunden, was durch Verbreiterung der sehr scharfen Linie mittels Argon erleichtert wird. Ferner wird ein bei hoherer Temperatur erscheinendes Absorptionsbandenspektrum des Sauerstoffs autgelost erhalten. Es wurde von etwa 1930 A.-E. an (Absorption schon bei Zimmertemperatur) bis tiber 2210 A.-E. hinaus photographiert, indem es bei bis 1050°fortschreitender Erhitzung ilberall intensiver wnrde und sich bis zu immer langeren Wellen verfolgen lieJl. Das Ent… Show more

“…In the 1930s E. Amaldi and E. Segré investigated spectra of highly excited alkali atoms in the presence of perturbing noble gas atoms [38,39] in Rome. Similar experiments were conducted simultaneously by C. Füchtbauer and coworkers in Rostock [40,41]. While it was expected that the polarizable medium would cause a red shift of the atomic resonances, the experiments revealed that both red and blue shifts are possible depending on the atomic buffer gas species and its density.…”

“…3. In the mean-field limit, the broadened line will become a Gaussian peak with a certain detuning from the atomic Rydberg state -the so called pressure shift -that was observed in the pioneering experiments [38][39][40][41] and interpreted by Fermi [42]. This shift is identical to the mean center of gravity <cg> and given by the average interaction energy with all ground-state atoms…”

“…All that remains is to solve the radial Schrödinger equation, 0 = − 1 2 d 2 dr 2 + l(l + 1) 2r 2 + V l (r) − E nl u nl (r). (4) We have specialized here to an l-dependent model potential V l (r) 6 . Many parameterizations of this potential exist.…”

“…Б, В и Г. каж-дая молекула газа поглощает независимо, и коэффициент поглощения пропорционален концентрации поглощающих молекул. Это расхождение было отнесено за счет молекулярных столкновений в смеси газов 158 и позднее объяснялось ударным уширенном молекулярной линии погло-щения 159 . Количественное исследование влияния различных непоглощаю-щих газов на интенсивность полос: поглощения 4,5ft N.,0 и 4,66μ СО (Т = 298° К) было проведено Гроссом и Даниэльсом 160 с помощью прибо-ра средней разрешающей силы.…”
