Sommerfeld extension of bohr theory

WebJun 30, 2024 · Sommerfeld extended Bohr's atomic model to include orbits of varying angular momentum, where the orbits are elliptical and become gradually less eccentric as the angular momentum increases [8, 9]. He quantized the angular and radial motion separately with quantum numbers for each but, as Bucher [ 10 ] discusses at length, he … WebIn 1913 Bohr proposed his quantized shell model of the atom (see Bohr atomic model) to …

WebIt got named spin back when people were working with the Bohr model and trying to extend it to atoms beyond hydrogen. Just as Bohr imagined that the atoms were little planets revolving around the nucleus as though it were a sun, other scientists tried to extend that idea by imagining that the little planets, just like real planets, had spin. Webtonian systems lead to Bohr-Sommerfeld theory, also called old quantum the-ory. Bohr [1] explained Planck’s hypothesis by the spectrum of the harmonic oscillator, which he obtained using his quantum conditions. Sommerfeld [19] extended Bohr’s quantization rules to a system with Hamiltonian H = p p2 +m2 + k r. (1)
