A comparison is made between the number of Efimov States present in /sup 4/He trimers as calculated using the Faddeev equations in the Faddeev coordinate-momentum approach with estimates predicted by N = (1/..pi..)ln(Vertical BaraVertical Bar/r/sub 0/) using realistic phenomenological He-He potentials. It is found that there is good agreement for systems supporting few states and that agreement remains when the Efimov states are forced to disappear by mathematically altering the potentials.
