Publishing such a script as part of your solution makes it "updated" and verifiable. While a complete, official "solution of elements of nuclear physics Meyerhof upd" remains unavailable in a single document, the collective wisdom of the nuclear physics community has produced a robust, fragmented, but navigable answer landscape. The true "solution" lies not in copying answers, but in understanding the bridge Meyerhof built from quantum mechanics to the nucleus.

He asks to derive this from the radial Schrödinger equation using the asymptotic wavefunction matching method.

Use the effective range expansion: [ k \cot \delta_0 = -\frac1a + \frac12 r_0 k^2 ] where (a) is scattering length and (r_0) is effective range. For n-p scattering, (a \approx -23.7) fm (singlet) and (r_0 \approx 2.7) fm.
