Exclusion principle repulsion effects on the covalent bond beyond the Born-Oppenheimer approximation
Sarsa A, Alcaraz-Pelegrina J, Le Sech C
Phys Chem Chem Phys
. 2019 May;
21(20):10411-10416.
PMID: 31065634
The changes in the covalent bond of the hydrogen molecule limited in space by a spherical hard boundary are studied. The sphere is moved along an axis parallel or orthogonal...

Int J Radiat Biol
. 2008 Jul;
84(7):603-11.
PMID: 18661376
Purpose: This work investigates whether a synergy in cell death induction exists in combining atomic ions irradiation and addition of platinum salts. Such a synergy could be of interest in...
