K-H_2 Quasi-molecular absorption detected in the T-dwarf epsilon Indi Ba

France Allard, Nicole F. Allard, Derek Homeier +3

T-type dwarfs present a broad and shallow absorption feature centred around 6950 A in the blue wing of the K doublet at 0.77 micron which resembles in depth and shape the satellite…

Formation and destruction of polycyclic aromatic hydrocarbon clusters in the interstellar medium

M. Rapacioli, F. Calvo, C. Joblin +3

The competition between the formation and destruction of coronene clusters under interstellar conditions is investigated theoretically. The unimolecular nucleation of neutral clust…

Electronic properties of Francium diatomic compounds and prospects for cold molecule formation

Mireille Aymar, Olivier Dulieu, Fernand Spiegelman

In this work we investigate the possibility to create cold Fr, RbFr, and CsFr molecules through photoassociation of cold atoms. Potential curves, permanent and transition dipo…

On the premelting features in sodium clusters

F. Calvo, F. Spiegelman

Melting in Na_n clusters described with an empirical embedded-atom potential has been reexamined in the size range 55<=n<=147 with a special attention at sizes close to 130. Contra…

Nucleation of a sodium droplet on C60

J. Roques, F. Calvo, F. Spiegelman +1

We investigate theoretically the progressive coating of C60 by several sodium atoms. Density functional calculations using a nonlocal functional are performed for NaC60 and Na2C60…

Theoretical study of the finite temperature spectroscopy in van der Waals clusters. III Solvated Chromophore as an effective diatomics

F. Calvo, F. Spiegelman, J. M. Mestdagh

The absorption spectroscopy of calcium-doped argon clusters is described in terms of an effective diatomics molecule Ca-(Ar_n), in the framework of semiclassical vertical transitio…
