pub fn complex_blatt_weisskopf(
m0: Float,
m1: Float,
m2: Float,
l: usize,
) -> Complex<Float>Expand description
Computes the Blatt-Weisskopf centrifugal barrier factor for a particle with mass $m_0$ and
angular momentum $\ell$ decaying to two particles with masses $m_1$ and $m_2$.
Note that this method uses an impact parameter of $0.1973\text{GeV}^{-1}$. Currently, only
values of $\ell <= 4$ are implemented.
