Question 10. Consider the scattering of neutrons by protons at very low energy due to a nuclear potential of range r0. Given that, cot(kr0 + δ) ≈ -ϒ/k where δ is the phase shift, k the wave number and (-ϒ)the logarithmic derivative of the deuteron ground state wave function, the phase shift is
Explanation:-
Answer: Option A. -> δ ≈ -k/ϒ - kr0-NA-
