Coulomb 2-Body System

This is the model of two particles interacting through Coulomb forces such as positronium, muonium, hydrogen atoms, deuterium atoms, etc.

Definitions

This model is described with the time-independent Schrödinger equation

\[ \hat{H} \psi(\pmb{r}) = E \psi(\pmb{r}),\]

and the Hamiltonian

\[ \hat{H} = - \frac{\hbar^2}{2\mu} \nabla^2 + V(r),\]

where $\mu=\left(\frac{1}{m_1}+\frac{1}{m_2}\right)^{-1}$ is the reduced mass of particle 1 and particle 2. The potential includes only Coulomb interaction and it does not include fine or hyperfine interactions in this model. Parameters are specified with the following struct.

Associated Legendre Polynomials

Antique.PMethod

P(model::CoulombTwoBody, x; n=0, m=0)

Rodrigues' formula & closed-form:

\[\begin{aligned} P_n^m(x) &= \left( 1-x^2 \right)^{m/2} \frac{\mathrm{d}^m}{\mathrm{d}x^m} P_n(x) \\ &= \left( 1-x^2 \right)^{m/2} \frac{\mathrm{d}^m}{\mathrm{d}x^m} \frac{1}{2^n n!} \frac{\mathrm{d}^n}{\mathrm{d}x ^n} \left[ \left( x^2-1 \right)^n \right] \\ &= \frac{1}{2^n} (1-x^2)^{m/2} \sum_{j=0}^{\left\lfloor\frac{n-m}{2}\right\rfloor} (-1)^j \frac{(2n-2j)!}{j! (n-j)! (n-2j-m)!} x^{(n-2j-m)}. \end{aligned},\]

where Legendre polynomials are defined as $P_n(x) = \frac{1}{2^n n!} \frac{\mathrm{d}^n}{\mathrm{d}x ^n} \left[ \left( x^2-1 \right)^n \right]$. Note that $P_l^{-m} = (-1)^m \frac{(l-m)!}{(l+m)!} P_l^m$ for $m<0$. (It is not compatible with $P_k^m(t) = (-1)^m\left( 1-t^2 \right)^{m/2} \frac{\mathrm{d}^m P_k(t)}{\mathrm{d}t^m}$ caused by $(-1)^m$.) The specific formulae are given below.

Lifetime of Positronium

The lifetime $\tau$ of positronium (Ps, $\mathrm{e}^+\mathrm{e}^-$) is written as

\[\tau = \frac{1}{\Gamma},\]

\[\Gamma = 4 \pi \alpha^4 c {a_0}^2 \langle\delta^3(\pmb{r})\rangle.\]

where $\langle\delta^3(\pmb{r})\rangle = \langle\psi|\delta^3(\pmb{r})|\psi\rangle = |\psi(\pmb{0})|^2 = \frac{1}{8\pi} a_0^{-3} \simeq 2.685\times10^{29}~\mathrm{m}^{-3}$ is the value of probability density at the origin ($r=0$). Reference:

Hyperfine Splitting

The hyperfine splitting of hydrogen atoms is given as

\[\Delta E (\mathrm{H}) = -\frac{2}{3} \mu_0 \gamma_\mathrm{p} \gamma_\mathrm{e} \hbar^2 \langle\delta^3(\pmb{r})\rangle\]

in Griffiths(1982). This fomula is not available for deuterium (D) and positronium (Ps). Because of the different spin between the proton and the deuteron for D, the contribution of positron-electron pair annihilation for Ps. Note the definition of gyromagnetic ratio. The mass of protons is used for all nucleons and nuclei:

\[\begin{aligned} &\gamma_\mathrm{e} = \frac{-e}{2 m_\mathrm{e}} g_\mathrm{e}, & &\gamma_\mathrm{e^+} = \frac{+e}{2 m_\mathrm{e}} g_\mathrm{e}, & &\gamma_\mathrm{\mu} = \frac{-e}{2 m_\mathrm{\mu}} g_\mathrm{\mu}, \\ &\gamma_\mathrm{p} = \frac{+e}{2 m_\mathrm{p}} g_\mathrm{p}, & &\gamma_\mathrm{d} = \frac{+e}{2 m_\mathrm{p}} g_\mathrm{d}, & &\gamma_\mathrm{t} = \frac{+e}{2 m_\mathrm{p}} g_\mathrm{t}, & &\gamma_\mathrm{h} = \frac{+2e}{2 m_\mathrm{p}} g_\mathrm{h}. & \end{aligned}\]

The value of probability density at the origin is $\langle\delta^3(\pmb{r})\rangle = \langle\psi|\delta^3(\pmb{r})|\psi\rangle = |\psi(\pmb{0})|^2 \simeq \frac{1}{\pi} a_0^{-3} \simeq 2.148\times10^{30}~\mathrm{m}^{-3}$ in Mu, H, D and T. This values are very different in Ps, $^3\mathrm{He}^+$ and muonic hydrogen ($\mathrm{p\mu}$) due to the difference of reduced masses and charges. The energy can be converted to frequency (Hz) by $v = \Delta E / h$.

Expected Value of $r$

\[\langle r \rangle = \int r |R_{nl}(r)|^2 r^2 \mathrm{d}r = \frac{a_\mu}{2Z} \left[ 3n^2 - l(l+1) \right] \\ a_\mu = a_0 \frac{m_\mathrm{e}}{\mu} \\ \frac{1}{\mu} = \frac{1}{m_\mathrm{e}} + \frac{1}{m_\mathrm{p}}\]

Expected Value of $r^2$

\[\langle r^2 \rangle = \int r^2 |R_{nl}(r)|^2 r^2 \mathrm{d}r = \frac{a_\mu^2}{2Z^2} n^2 \left[ 5n^2 + 1 - 3l(l+1) \right] \\ a_\mu = a_0 \frac{m_\mathrm{e}}{\mu} \\ \frac{1}{\mu} = \frac{1}{m_\mathrm{e}} + \frac{1}{m_\mathrm{p}}\]

Virial Theorem

The virial theorem $2\langle T \rangle + \langle V \rangle = 0$ and the definition of Hamiltonian $\langle H \rangle = \langle T \rangle + \langle V \rangle$ derive $\langle H \rangle = \frac{1}{2} \langle V \rangle$ and $\langle H \rangle = -\langle T \rangle$.

\[\frac{1}{2} \int \psi_n^\ast(x) V(x) \psi_n(x) \mathrm{d}x = E_n\]
