Pauli Susceptibility of a 3 C 60 (a=k, Rb)
The Pauli paramagnetic susceptibility of A3C60 (A= K, Rb) compounds is calculated. A lattice quantum Monte Carlo method is applied to a multi-band Hubbard model, including the on-site Coulomb interaction U. It is found that the many-body enhancement of the susceptibility is of the order of a factor of three. This reconciles estimates of the density of states from the susceptibility with other e...
متن کاملK rate coefficients for the reaction of OH with i − C 3 H 7 I , n − C 3 H 7 I and C 3 H 8
The kinetics of the title reactions were investigated using the laser photolysis resonance fluorescence method, employing the sequential two-photon dissociation of NO2 in the presence of H2 as the OH source. The 298 K rate constant for OH + C3H8 was found to be (1.15 ± 0.1) × 10−12 cm s−1, in excellent agreement with the literature recommendation, and with a separate determination using HNO3 ph...
متن کاملEffects of Nonstoichiometry in a 3−x C 60 (a= K, Rb)
We perform self-consistent Hartree calculations for a model of A 3−x C 60 (A= K, Rb) to study the effects of the presence of vacancies. We find that the strong vacancy potential is very efficiently screened and that the density of states is only weakly influenced by the presence of vacancies.
متن کاملExperimental and theoretical investigations of the thermodynamic stability of Ba-c(60) and K-C(60) compound clusters.
A novel experimental set-up was used to study superstable (magic) Ba-C(60) and K-C(60) compound clusters. The most stable systems observed cannot be rationalized by simple electronic or by geometrical shell filling arguments. Annealing the clusters past the temperature necessary for the fragmentation of the initial metastable clusters formed at the source reveals information about their thermod...
