Web21 feb. 2016 · P ( r) d r = 4 π r 2 R ( r) 2 d r. The argument is that the volume of spherical shell between r and r + d r is 4 π r 2 d r and Radial probability density is R ( r) 2. Hence the probability of finding the electron in r and r + d r is 4 π r 2 R ( r) 2 d r. There is an apparent discrepancy of a factor of 4 π. Could someone explain this?
