+ | |||
+ | The operator representing the potential in second quantisation is given as: | ||
+ | $$ O = \sum_{n'', | ||
+ | For the quantisation of the wave-function (physical meaning of the indices n,l,m) we can choose a basis of spherical harmonics times some radial function, i.e. $\psi_{n, | ||
+ | $$ A_{n'' | ||
+ | Note the difference between the function $A_{k,m}$ and the parameter $A_{n'' | ||
+ | |||
+ | |||
+ | ### | ||
+ | |||
+ | |||
+ | |||

+ | |||
