Formulation of the equation of state (EoS) of nuclear matter has far-reaching implications for issues ranging from the atomic nucleus to crucial aspects of astrophysics. Recent investigations of the influence of the formation of light ion clusters on the development of the EoS are of interest. A study based on a generalized relativistic mean-field model revealed an isotope-dependant quenching of α-clustering on the surface of Sn as the nuclear system becomes more asymmetric. This trend of decreasing α-clustering with increasing mass number of Sn was previously found to be consistent with existing experimental results of an α- pickup reaction. The implications of predictions of the EoS are discussed as being of profound interest to proton-induced α-particle pre-equilibrium emission at incident energies above about 100 MeV.
