Quasiclassical quantum defect theory and the spectrum of highly excited rubidium atoms

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Radiative lifetimes of highly excited states in rubidium

2014 Measurements have been made of the natural radiative lifetimes of highly excited rubidium (9 ~ n ~ 18) S and D states. These results, as well as those already published concerning P and F states, agree well with the theoretical lifetimes calculated by the Bates-Damgaard method. J. Physique 41 (1980) 119-121 1 FTVRIER 1980, Classification Physics Abstracts 32.70 In the past few years, measu...

A comparison of quantum and quasiclassical statistical models for reactions of electronically excited atoms with molecular hydrogen.

A detailed comparison of statistical models based on the quasiclassical trajectory (SQCT) and quantum mechanical (SQM) methods is presented in this work for the C((1)D)+H(2), S((1)D)+H(2), O((1)D)+H(2) and N((2)D)+H(2) insertion reactions. Reaction probabilities, integral (ICS) and differential (DCS) cross sections at different levels of product's state resolution are shown and discussed for th...

Effects of Magnetic and Electric Fields on Highly Excited Atoms

Is the spectrum of highly excited mesons purely coulombian?

We show that a static central potential may provide a precise description of highly excited light unflavored mesons. Because of string breaking, this potential becomes of chromoelectric type at sufficiently large quark-antiquark distances giving rise to a Coulombian spectrum. The same conclusion can be inferred for any other meson sector through a straightforward extension of our analysis.
