Abstract: | We calculate potential energies for charged and neutral jellium clusters which fragment in two pieces, in the framework of the liquid drop model plus Strutinsky shell corrections obtained from the two-centre harmonic oscillator. We consider the symmetric fragmentation of Na 4 + 2 + , Na 1 + 8 + , and Na38. Good agreement is found with results obtained by self-consistent methods, which are much more involved. |
