Which R and Angular Parts Create a 2p Wave for 2p to 1s Transition?

[georg gill]

Homework Statement

I am trying to calculate the selection rules from 2p to 1s. Above are the three results in (1152)-.(1154). And In the image one also finds the spherical harmonics factors. I can not determine which R and angular parts that give the three 2p waves. Can you show which ones that will create one of the 2p waves and integrate the radial (radius part) part of that integral?

I get the right answer for the y comp except that I cn not get rid of the $$\pm$$. the answer for the y-comp is given in (1153).
