We describe several new techniques for obtaining detailed information on the exponential falloff of discrete eigenfunctions of N-body Schrödinger operators. An example of a new result is the bound (conjectured by Morgan) {Mathematical expression} for an eigenfunction ω of {Mathematical expression} with energy EN. In this bound r1r2... rN are the radii |xi| in increasing order and the α's are restricted by αn<(En-1-En)1/2, where En, for n=0, 1,..., N-1, is the lowest energy of the system described by Hn. Our methods include subharmonic comparison theorems and "geometric spectral analysis".
