The statistical model is the main model to approach the description of the evaporation process but in some extreme conditions such as high core excitation temperatures or high angular momentum, shows discrepancies with the behavior of the real nuclei. The thesis investigates what is indicated as a possible missing ingredient for full compatibility between simulations and real data in these high-temperature excitation regions: the nuclear stratosphere. After the formation of the compound nucleus, a hot very diffuse nuclear surface so is formed and promotes evaporative like-emission prior to its relaxation. The study of this particular condition is carried on a double way: on the one hand, an adaptation work of existing codes, by modifying the systematics of the ingredients used by the statistical model and consolidating the same codes, by constantly comparing simulations with the results obtained in the literature; on the other hand, the use of the same codes to explore case of extreme conditions of temperatures or angular momentum using systematics related to the nuclear stratospheres in order to highlight the possible exploitation of this feature for the production of stable superheavy nuclei.
