Abstract
We present an experimental study of the AC conductance GAC of an atomic force microscope engraved quantum point contact at high frequency f=160 MHz. In agreement with theoretical predictions the real part R(GAC) is unchanged from the DC-conductance GDC. The imaginary part I(G AC) changes for every addition of a new conductance channel.
