Abstract

We study the near-threshold (E-->0) behavior of quantum systems described by an attractive or repulsive 1/r^2 potential in conjunction with a shorter-ranged 1/r^m (m>2) term in the potential tail. For an attractive 1/r^2 potential supporting an infinite dipole series of bound states, we derive an explicit expression for the threshold value of the pre-exponential factor determining the absolute ...
