Nucleon-nucleon phase shifts for all partial waves, static properties, and electromagnetic form factors of the deuteron are calculated from an NN potential, which has a mesonic sector with only two adjusted parameters and is supplemented by a phenomenological six-quark core potential with a P-matrix-type parametrization. NN phase shifts constrain the six-quark core radius within 1 less than or equal tobless than or equal to1.2 fm. The deuteron's magnetic structure function B agrees with the data only for b = 1 fm. The six-quark core probability is about 2.3%.
