摘要/Abstract

摘要： Intermittency and fractal behaviour have been studied of emission spectra of target associated fragments from $^{84}$Kr--AgBr interactions at 1.7\,A GeV in emission angle space and azimuthal angle space separately. The intermittent behaviour is observed in the two spaces separately. From the intermittency exponent, the anomalous fractal dimension $d_{q}$ is calculated and the variation of $d_{q}$ with the order $q$ is investigated. It is found that the anomalous dimensions are found to increase with the order of moments $q$, thereby indicating the relation of multifractality to production mechanism of target associated fragments.
