Talk:Patterson function

Can any one add which Patterson is responsible for this function...? -- User:Stillnotelf from 152.2.49.238 15:21, 9 August 2006 (UTC)

electron density convolved with its inverse??

Isn't it rather electron density convolved with the electron density at a point displaced by the vector u?

The formula presented is

$P({\vec {u}})=\rho ({\vec {r}})*\rho (-{\vec {r}})$

but how can we have ${\vec {r}}$ on the right hand and ${\vec {u}}$ on the left hand side? Shouldn't it rather be:

$P({\vec {u}})=\rho ({\vec {r}})*\rho ({\vec {r}}+{\vec {u}})$?
