Description
Comparative analyses of evaporative light particle energy and angular distributions within the Statistical Model (SM) framework indicate nuclear deformations at high spin significantly larger than those predicted by the Rotating Liquid Drop Model. Examples of light N=Z systems showing this behaviour are the 56Ni, 44Ti and 40Ca nuclei.
The clustering might be an important structural feature. On this basis the cranked cluster model was developed and the calculations suggested the presence of quasistable deformed cluster configurations at high angular momenta and excitation energies in 48Cr and 36Ar nuclei [1].
Following this view, we have undertaken the study of nuclear deformations of the 48Cr and 36Ar compound nuclei via the emission of charged particles [2,3].
Light charged particles were measured with the 8πLP detector array and a wide set of exclusive observables have been extracted and compared with SM simulations performed with the code LILITA_N21 [4].
The results of this analyses and the future investigation exploiting the advanced performances offered by the Time-of-flight spectrometer TOSCA [5] will be discussed.
