Multiple-electron losses of highly charged ions colliding with neutral atoms

We present calculations of the total and m-fold electron-loss cross sections using the DEPOSIT code for highly charged U(q+) ions (q=10,31,33) colliding with Ne and Ar targets at projectile energies E=1.4 and 3.5 MeV/u. Typical examples of the deposited energy T(b) and m-fold ionization probabilities Pm(b) used for the cross-section calculations as a function of the impact parameter b are given. Calculated m-fold electron-loss cross sections are in a good agreement with available experimental data. Although the projectile charge is rather high, a contribution of multiple-electron loss cross sections to the total electron-loss cross sections is high: about 65% for the cases mentioned.Comment: 6 pages, 4 figure

The DEPOSIT computer code: calculations of electron-loss cross sections for complex ions colliding with neutral atoms

A description of the DEPOSIT computer code is presented. The code is intended to calculate total and m-fold electron-loss cross sections (m is the number of ionized electrons) and the energy T(b) deposited to the projectile (positive or negative ion) during a collision with a neutral atom at low and intermediate collision energies as a function of the impact parameter b. The deposited energy is calculated as a 3D-integral over the projectile coordinate space in the classical energy-deposition model. Examples of the calculated deposited energies, ionization probabilities and electron-loss cross sections are given as well as the description of the input and output data.Comment: 11 pages, 3 figure

The DEPOSIT computer code based on the low rank approximations

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present a new version of the DEPOSIT computer code based on the low rank approximations. This approach is based on the two dimensional cross decomposition of matrices and separated representations of analytical functions. The cross algorithm is available in the distributed package and can be used independently. All integration routines related to the computation of the deposited energy T ( b ) are implemented in a new way (low rank separated representation format on homogeneous meshes). By...
