WebSep 12, 2024 · Strategy. If we assume that the proton confined in the nucleus can be modeled as a quantum particle in a box, all we need to do is to use Equation 7.5.11 to find its energies E 1 and E 2. The mass of a proton is m = 1.76 × 10 − 27 k g. The emitted photon carries away the energy difference Δ E = E 2 − E 1. WebApr 21, 2024 · The quantum numbers have names: \(n\) is called the principal quantum number, \(l\) is called the angular momentum quantum number, and \(m_l\) is called the magnetic quantum number because (as we will see in Section 8.4) the energy in a magnetic field depends upon \(m_l\).Often \(l\) is called the azimuthal quantum number because it … WebMar 5, 2024 · The state \(\psi_A= \uparrow_x\rangle\) is called a pure state, it’s the kind of quantum state we’ve been studying this whole course..
