PRACTICE / Characteristic and continuous X-ray spectra
Recover the screening offset
For one characteristic line series, measured values fit √(f/f₀) = a(Z − σ), where f₀ is a fixed positive reference frequency. The dimensionless ordinate is 4 at Z = 22 and 6 at Z = 32.
What screening parameter σ follows from this model?
Organize the givens & assumptions
- (Z, √(f/f₀)): (22, 4), (32, 6)
- Same line series and reference frequency
Treat the two points as exact for this exercise and assume a constant effective screening parameter over the interval.
- A
- B
- C
- D
