Webthe ﬁne structure constant and the rest energy of the electron. The ﬁne structure constant is given by α ≡ e2 ~c ≃ 1 137, (2.1.4) and the rest energy of the electron is mc2. Then, e2 a 0 = me4 ~2 = mα2~2c2 ~2 = α2 mc2. (2.1.5) This states that the energy scale of hydrogen bound states is a factor of α2 smaller than WebApr 3, 2015 · A larger fine-structure constant would make the electrons bind more tightly to nuclei, make atoms smaller (which also makes macroscopic objects smaller) and increase chemical binding energies. The opposite direction would have the opposite effects. There is no known relation between fine-structure constant and gravity.

WebDec 3, 2024 · The fine-structure constant, first introduced in 1916, describes the strength of the electromagnetic interaction between light and charged elementary particles, like electrons and muons. WebNow, mass is equivalent to energy, of course: it’s just a matter of units, so we can equate m e with E e (this amounts to expressing the energy of the electron in a kg unit—bit weird, but OK) and so we get: E e = α e /r e. So there we have: the fine-structure constant α e is Nature’s ‘cut-off’ factor, so to speak. csph cameroon
