An experimental study of the cyclotron resonance of hot holes in germanium was carried out at 1.6°K making use of 6 mm microwaves. The half widths of the resonance lines for light holes, heavy holes and electrons were observed as functions of the microwave power falling on the specimen. It was found that when a large microwave power fell on the specimen, the increase in the width of the light hole line was nearly the same as that of heavy hole. This fact can reasonably be interpreted, because light and heavy holes are strongly coupled by the interband transition.
