Calculate the velocity of an electron that has a wavelength of 0.265 nanometers. The mass of an electron is 9.11x10^-28. What energy of photon will have the same wavelength as a 50keV electron? What is the wavelength of a photon emitted when an electron in hydrogen goes from ...
In beta decay, a neutron in the nucleus spontaneously turns into a proton, an electron and a third particle called an antineutrino. The nucleus ejects the electron and antineutrino, while the proton remains in the nucleus. The ejected electron is referred to as a beta particle. The nucleus ...
The ejected electron is referred to as a beta particle. The nucleus loses one neutron and gains one proton. Therefore, a hydrogen-3 atom undergoing beta decay becomes a helium-3 atom. Spontaneous Fission An atom actually splits instead of throwing off an alpha or beta particle in spontaneous...
The amount of energy required to remove the electron from the orbit of an atom is known as ionization energy. When the electron gets removed from the atom, it forms an ion.Answer and Explanation: Write the expression for the ionization energy for hydrogen atom fr...
The unbound material, or ejecta, is characterized by total mass, average velocity, and electron fraction Ye np=ðnn þ npÞ where nn and np are the number densities for neutrons and protons, respectively. More detailed treatments consider additional behavior, such as the spatial and ...
al. have done here is they compared the x-ray image of the cluster (where you can clearly see the results of the collision: one cluster has "punched through" the other) to the gravity lensing mass reconstruction of the cluster. They find that the mass is around the galaxies (wh...

L. Verschuur, 1999, 5 [this paper is principally concerned with presenting an observational result; however, it does introduce 'critical ionization velocity' (CIV) and seeks to relate the observations to CIV. CIV is interesting, and the topic of some research. AFAIK, no unambiguous signatur...
Since electrons in low-lying orbits in heavy atoms move with relativistic velocity, non-relativistic analysis is insufficient to estimate the minimum radius of the electron orbits: it is necessary to involve relativistic mechanics. Elsewhere we will give in detail a relativistic generalization (reported...
