ABSTRACT:
A high-gain Josephson-type two-particle tunneling detector is positioned in a borehole penetrating an earth formation and tuned for response in a frequency range of 8400 to 9600 gigahertz. Result: IR emission due to "stretching" vibration of the C-H bonds of adjacently situated hydrocarbons can be detected in surprising fashion.
