Again f is small compared to g (except at very small r) because when k is positive the first terms dominate, and α is big compared to γ− k, whereas when k is negative the second terms dominate and α is small compared to γ− k. Note that the dominant term is quite similar to corresponding the Schrödinger solution – the upper index on the Laguerre polynomial is slightly less (2γ+1 or 2γ−1 rather than 2ℓ+1, which is the nearest integer), as is the power of ρ (γ or γ−1 instead of ℓ, the nearest integer). The exponential decay is slightly faster than in the Schrödinger solution.
