Edited sentence: Fusion reactions utilizing 48Ca nuclei usually produce compound nuclei with intermediate excitation energies (~30-35 MeV) and are sometimes referred to as "warm" fusion reactions.The excited nucleus then decays to the ground state via the emission of 3-5 neutrons.These are processes which create compound nuclei at high excitation energy (~40-50 MeV, hence "hot"), leading to a reduced probability of survival from fission and quasi-fission.This leads, in part, to relatively high yields from these reactions.This section deals with the synthesis of nuclei of ununpentium by so-called "hot" fusion reactions
