2 days ago · Louis de Broglie hypothesized that this is true for all particles, even particles which have mass such as electrons. He showed that, assuming that the matter waves propagate along with their particle counterparts, electrons form standing waves , meaning that only certain discrete rotational frequencies about the nucleus of an atom are allowed. [35]
3 days ago · In 1923, the French physicist Louis de Broglie put forward his theory of matter waves by stating that particles can exhibit wave characteristics and vice versa. Building on de Broglie's approach, modern quantum mechanics was born in 1925, when the German physicists Werner Heisenberg, Max Born, and Pascual Jordan [92] [93] developed matrix ...
3 days ago · When the double-slit experiment is performed using electrons instead of photons, the relevant wavelength is the de Broglie wavelength \(\lambda:\) \[\lambda = \frac{h}{p},\] where \(h\) is Planck's constant and \(p\) is the electron's momentum.
4 days ago · We characterize in a novel manner the physical properties of the low temperature Fermi gas in the degenerate domain as a function of temperature and chemical potential. For the first time we obtain low temperature T results in the domain where several fermions are found within a de Broglie spatial cell. In this regime, the usual high degeneracy Sommerfeld expansion fails. The other known semi-classical Boltzmann domain applies when fewer than one particle is found in the de Broglie cell. We ...

3 days ago · Hence, the kinetic energy of α α particle is = 1.722 × 10−11eV = 1.722 × 10 − 11 e V . Note: In case of electrons going in circles around the nucleus in atoms, de Broglie waves exist as a closed loop such that they can exist only as standing waves and can fit evenly around the loop.
3 days ago · Otto Hahn ( pronounced [ˈɔtoː ˈhaːn] ⓘ; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium.
