ABSTRACT
In Chapter 10 we found the differential cross section for the absorption of radiation of frequency ω by an atom and removal of an electron into the continuum. This is the experimental condition for the photoelectric effect, which we now study in detail. In Chapter 10, the differential cross section was found to be d σ ( θ , φ ) d Ω = e 2 2 πmc k f ω | ∫ u f * e i k ⋅ r P ⋅ ∇ u n dτ | 2 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429493645/749bab20-4a79-4f5a-8c66-d9e9a36a87b9/content/eq1081.tif"/>
