Abstract
- Experimental data on compound multiplicity distribution produced in 24Mg-AgBr and 12C-AgBr interactions, both at 4.5A GeV, have been analysed in terms of scaled factorial moments. We have calculated the values of generalized dimension Dq for q = 2, 3, 4, 5, 6 and 7 with the help of intermittency exponent αq. From the knowledge of Dq, the multifractal specific heat is calculated for different multiplicity bin ranges. The parameter λq (λq = (αq + 1)/q) is calculated from αq to look for possible non-thermal phase transition. The analysis reveals no evidence of nonthermal phase transition. Instead, different specific heat in different multiplicity bins has been observed.<br />Analizirali smo eksperimentalne podatke o raspodjelama složene višestrukosti u sudarima 24Mg-AgBr i 12C-AgBr, oba na 4.5A GeV, primjenom prilagodnih faktorijalnih momenata. Izračunali smo vrijednosti poopćene dimenzije Dq za q = 2, 3, 4, 5, 6 i 7 pomoću eksponenta prekidanja αq. Te vrijednosti Dq primijenili smo za izračunavanje višefraktalne specifične topline za niz pretinaca. Parametar λq (λq = (αq + 1)/q) smo izračunali na osnovi αq tražeći netermički fazni prijelaz. Analiza nije pokazala prisutnost netermičkog faznog prijelaza, ali smo našli različite specifične topline u pretincima.
