K-H_2 Quasi-molecular absorption detected in the T-dwarf epsilon Indi Ba (2007)

Allard, France, Allard, Nicole F., Homeier, Derek, Kielkopf, John, McCaughrean, Mark J., Spiegelman, Fernand

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 absorption...

Quantum Effects on the Caloric Curves of Lithium Clusters (2007)

Spiegelman, Fernand, Calvo, Florent

A tight-binding quantum Hamiltonian and an empirical embedded-atom model (EAM) potential are used to get insight into the finite-temperature behavior of small Lin clusters, n = 8, 20, and 55....

Electronic properties of Francium diatomic compounds and prospects for cold molecule formation (2006)

Aymar, Mireille, Dulieu, Olivier, Spiegelman, Fernand

In this work we investigate the possibility to create cold Fr$_2$, RbFr, and CsFr molecules through photoassociation of cold atoms. Potential curves, permanent and transition dipole moments for the...
