Question 1 of 30

Time left: 00:00

For a hydrogen-like ion with nuclear charge \(Z\), consider the electric-dipole (E1) spontaneous emission rate from \(n=2\to n=1\). Ignoring relativistic corrections, how does the transition rate \(A_{2\to 1}\) scale with \(Z\)?

Select one option.

\(A_{2\to 1}\propto Z\)
\(A_{2\to 1}\propto Z^2\)
\(A_{2\to 1}\propto Z^4\)
\(A_{2\to 1}\propto Z^6\)
\(A_{2\to 1}\) is independent of \(Z\)
