Abstract
Kinetic energy release distributions are reported for the emission of C-2 from the positive ions of C-60, Ne@C-60, C-82 and La@C-82. Finite heat bath theory was applied to deduce the C-2 binding (vaporization) energies, Delta E(vap). The results obtained are: Delta E(vap)(C(6)0()) = 7.1 +/- 0.5 eV, Delta E(vap) (Ne@C-60(+)) = 7.4 +/- 0.5 eV; Delta E(vap)(C-82(+)) = 6.1 +/- 0.4 eV and Delta E(vap)(La@C-82(+)) = 7.3 /- 0.4 eV. The endohedral neon atom has a minor effect on the cage bin ding, while lanthanum has a relatively strong effect.
