Abstract
The surface temperatures of the plasma core in the final stages of the first contraction
phase of spark-generated bubbles oscillating under ordinary laboratory conditions in a large expanse of
water are determined experimentally. The measurement method is based on an analysis of the optical
radiation from the bubbles and on the assumption that the plasma core is radiating as a black-body. It
is found that the maximum surface temperatures of the plasma core range 4300–8700 K.
