Charge transfer in collisions of protons with water molecule at high projectile energies and small scattering angles

Single and multiple electron removal and fragmentation in collisions of protons with water molecules

“…On the theoretical side, semiempirical methods have been used to evaluate the total and differential cross sections for single ionization of the H 2 O molecule [16,17]. Also, treatments based on the first Born [9,[18][19][20] and the continuum distorted-wave-eikonal initial state (CDW-EIS) [21][22][23] approximations have been applied to describe primary processes that happen in the collision of water with heavy ions. In all these treatments, within the framework of the independent electron picture, mostly single electron transitions are considered.…”

Single- and multiple-electron processes in water molecules colliding with proton beams

“…To calculate differential cross sections and total cross sections (TCSs) for the ionization of H 2 O molecules, a number of semi-empirical methods have been applied [7][8][9][10]. Also, descriptions based on the Born approximation [11][12][13][14] and on different versions of the various continuum distorted wave-eikonal initial state models [9,[15][16][17] have been considered to describe the ionization or capture reactions resulting from the collision of heavy ions with H 2 O-vapor targets. Investigations of multiple ionization, capture and transfer-ionization processes for ion−H 2 O systems have also been performed in the framework of the nonperturbative basis generator method (BGM) [18] and using the classical trajectory Monte Carlo (CTMC) treatment [19][20][21][22].…”
