SUMMARY
The discussion centers on the photoemission cross-section from the 1s state of a charge Z atom, establishing that the cross-section, denoted as σ, is proportional to Z^5 in the limit where p_fa_0/Zħ >> 1. The equation for σ is provided as σ = (128a_0^3πe^2p_f^3)/(3mħ^3ω_c[1+p_f^2a_0^2/ħ^2]^4). A key point raised is the transformation of the Bohr radius a_0 to a_0/Z, which is attributed to the change in the Coulomb potential in the Hamiltonian from q^2/r to Zq^2/r.
