This scientist and Walther Ritz name a “combination principle” that generalizes (-5[1])an equation (10[1])developed by this scientist. (-5[1])Serge Haroche (“ah-ROSH”) used highly excited states named for this scientist to study photons (10[1])trapped in an optical (10[1])cavity. (10[1])Using a reduced (-5[1])mass term allows for a constant named for this scientist to account (10[1])for finite masses. (10[1])This scientist’s namesake constant is equal to the fine structure (10[1])constant (10[1]-5[1])over 4 pi (-5[1])times (-5[1])the Bohr radius and is usually subscripted (10[2])infinity. (10[1])An exotic atom that could theoretically hold many atoms within it is this (10[1])scientist’s namesake (10[1])polaron. An equation named for this scientist is used to derive the Lyman and Balmer (10[1])spectral (10[2])series (10[1])for hydrogen. (10[3]-5[1])For 10 points, (10[1])what (10[1]-5[1])Swedish physicist names a formula (10[2])for emissions from electronic transitions in an atom? (10[1])■END■ (10[2]0[18])
