For instance, good agreement between calculation results and experimental data can be achieved only by resorting to unrealistic parameterizations that do not ensure the simultaneous reproduction of all experimental observables. Therefore, a collection of a large dataset including many observables is needed in order to calculate the suitable parameters for different reactions. In general, the global failure of the model can be attributed to the lack of dynamics in describing the evolution of the excited system, suggesting the need for essential ingredients in the standard SM that can be investigated by reanalyzing the systems that show larger discrepancies. Large discrepancies between experimental data and simulations for compound nuclei with mass number A = 150 have been evidenced in energy spectra, angular distributions, and multiplicities of neutrons, protons, and \(\alpha\)-particles [4; 5; 6; 7; 8; 9; 10]. Although different modifications of the standard SM parameters have been considered, none of them permits simultaneous reproduction of the wide set of experimental observables available. These limitations can be ascribed to the incorrect treatment of the problem and to the competition with the fission channel. However, difficulties in reproducing the experimental data have been observed in the mass region around A = 60 at very high angular momenta, where the competition with the fission channel can be considered negligible. Examples include the 120 MeV \({}^{30}\)Si +\({}^{30}\) Si reaction [11], where the \(\alpha\)-particle energy spectra were much softer than simulated ones, resulting in their being shifted at a higher energy with a significantly broader distribution, and the 190 MeV \({}^{40}\)Ar + \({}^{27}\)Al [12] reaction, which is the subject of the present reanalysis. The global behaviour observed in these two systems was the reason for our invoking the need for new physics in the statistical model [12]. Several attempts to correct the standard SM and to return to satisfactory overall pictures for these extreme cases have failed. Often, they allowed correct reproduction of only one observable at a time. For instance, in the work of [PERSON] et al. [12], assuming emission from very deformed nuclei with a near-prolate shape, with ratios of major-to-minor axes of the deformed emitter up to 3, and with the reduction of the Coulomb barriers, it was possible to reproduce \(\alpha\)-particle energy spectra and proton and \(\alpha\)-particle multiplicities, though not the proton energy spectra. The lesson learned is that it is crucial to consider a large set of observables in order to avoid controversial conclusions. At present, a global solution is missing, although these limitations of the standard SM have been known for decades and the behaviour of reaction systems at high energy and spin represents a benchmark for studies of new frontiers. The introduction of the nuclear stratosphere model [13] is aimed at eliminating effects due to deformations and variations of the channel competition at extreme angular momentum. In fact, the observed trends of the energy spectra and angular distributions can be related to the occupation of high-lying single-particle levels occurring with the increase of the nuclear temperature, which consequently changes the distribution of nuclear density. More generally, at high temperatures when the nucleus is more excited a balance between the density distribution decrease in the inner core and its increase in the surrounding stratosphere should be pursued. This balance is achieved by the contraction of the volume part and the expansion of that part of the surface employing high single-particle orbits. In this work, after a brief description of the recently-developed computer code LILITA_N21 [14], the reanalysis of the light charge particle observables collected in the 190 MeV \({}^{40}\)Ar + \({}^{27}\)Al [12] reaction and the SM ingredients used to describe the evaporative decay process are discussed.
