A comparison of spectra of SBSL produced by standard method and by JB mechanism

Recently new mechanism to create single bubble sonoluminescence was discovered. Main features of new mechanism is jet and bubble correlated with this jet which undergoes sonoluminescence. This mechanism will be referenced here as JB mechanism to produce Single Bubble Sonoluminescence (SBSL). JB mechanism extends parameter space where SBSL can be observed. When full theoretical understanding is missing, natural question is if properties of SBSL are the same if SBSL is produced by different mechanisms. Partially this question was already addressed in original paper. Conclusion was that within resolution of the apparatus there are no significant differences between SBSL produced by standard or JB mechanism (in terms of amplitude of signal, duration of flash). Aim of this paper is to compare spectra produced by SBSL created by standard method\cite{gaitan} and by JB mechanism.

The new method to create Single Bubble Sonoluminescence

Sonoluminescence is a phenomenon which is known for some time, relatively easy to produce but still not fully understood. A milestone was discovery of procedure for creating Single Bubble Sonoluminescene (SBSL) \cite{gaitan} in 1989. Sonoluminescence in single bubble at well defined conditions, periodically produced for a long time, is well suited for a systematic study. This procedure for SBSL was for many years considered as standard one for a study this interesting phenomenon. About single bubble sonoluminescence was published wealth of sometime very surprising results, however generally accepted solution to the problem is still missing. Another way (technique based on water hammer) to produce sonoluminescence was published in 2003 \cite{waterham}. By this method many orders of magnitude stronger signal in comparison with standard procedure can be produced and also new phenomena have been observed. In this paper we describe another method to produce relatively stable SBSL. New technique is closely related to standard one. But it for example does not need degassing of working liquid and there is one more handle for a study of the sonoluminescence.
