<p>Processes that take place in the participant and spectator regions of interacting nuclei poses a significant obstacle to comprehend the nucleus–nucleus (A–A) interactions, given the central character of the reactions. An essential parameter for gaining a thorough understanding of the response processes in A–A interactions is the analysis of angular distributions (ADs) in the final-state particles in the target fragmentation zone. By offering a full 4<InlineEquation ID="IEq5"> <EquationSource Format="TEX">\(\pi \)</EquationSource> <EquationSource Format="MATHML"><math> <mi>π</mi> </math></EquationSource> </InlineEquation> angular coverage, nuclear emulsion detectors (NEDs) enable almost thresholdless detection of shower, black and grey particles, referred to as fast target protons (FTP).

These ADs are examined using the modified Maxwell–Boltzmann statistical (MBS) model for a range of <InlineEquation ID="IEq7"> <EquationSource Format="TEX">\(N_{h}\)</EquationSource> <EquationSource Format="MATHML"><math> <msub> <mi>N</mi> <mi>h</mi> </msub> </math></EquationSource> </InlineEquation>-values (target sizes) and <i>Q</i>-values (projectile spectator charges). It is evident that the ADs of these target protons satisfy the nuclear limiting fragmentation (NLF) theory, which is unaffected by the <InlineEquation ID="IEq8"> <EquationSource Format="TEX">\(N_{h}\)</EquationSource> <EquationSource Format="MATHML"><math> <msub> <mi>N</mi> <mi>h</mi> </msub> </math></EquationSource> </InlineEquation>-values and <i>Q</i>-values.
