The isoscalar E2 charge for a closed shell plus one nucleon is studied by three methods: (a) a trial product wave function with uniform scaling of the oscillator length parameters; (b) Random Phase Approximation (R.P.A.), (c) a less restricted trial product wave function. Whereas the first two methods give quite different results, the last two are essentially identical.
