Summary
Finite-temperature Hartree-Fock calculations in24Mg seem to indicate that the lowest-lying prolate, oblate and spherical solutions exhibit unexpected structure in the internal energy atT⋍(0.5÷1.0) MeV. For these solutions the ensemble average of the centre-of-mass kinetic-energy operator exhibits similar structure in the same temperature range, which leads us to believe that the centre of mass is not necessarily thermally quiescent.
Riassunto
Calcoli a temperatura finita del tipo di Hartree-Fock in24Mg sembrano indicare che le soluzioni che giacciono nello strato piú basso, prolate, oblate e sferiche mostrano un’inattesa struttura nell’energia interna aT⋍(0.5÷1.0) MeV. Per queste soluzioni, la media d’insieme dell’operatore dell’energia cinetica del centro di massa mostra una struttura simile nello stesso intervallo di temperatura, che ci porta a credere che il centro di massa non sia necessariamente termicamente quiescente.
