摘要：

charging a thin wire we realize a pure attractive 1/r(2) potential of variable strength for cold neutral atoms. Scattering experiments are performed where the charged wire is placed inside a confined gas of cold lithium atoms. We observe the "falling" of atoms into the 1/r(2) singularity which so far has been only theoretically discussed in textbooks. [S0031-9007(98)06725-8].
