Abstract: Cooper pair sizes are evaluated in a simple harmonic oscillator modelreproducing the values of sophisticated HFB calculations. Underlying reasonsfor the very small sizes of 2.0-2.5 fm of Cooper pairs in the surface of nucleiare analysed. It is shown that the confining properties of the nuclear volumeis the dominating effect. It is argued that for Cooper pair sizes LDA isparticularly inadapted.
