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... Title of program: DEPOSIT 2014 Catalogue Id: AENP_v2_0 Nature of problem For a given impact parameter b to calculate the deposited energy T(b) as a 3D integral over a coordinate space, and ionization probabilities P m (b). For a given energy of the projectile to calculate the total and m-fold electron-loss cross sections using T(b) values on the whole b-mesh.
