CasP version 5.0  (April 2011)


CasP version 4.1 (Dezember 2009)

  • Improved treatment of the shell corrections for lineshape asymmetry
  • Improved accuracy for numerical integrations and interpolations

CasP version 4.0 (July 2008)

  • Modification on how BLOCH and SHELL CORRECTIONS are implemented
  • Internal charge number for the UCA scaling for screened projectiles was improved
  • Close collision function h was replaced by an accurate fit formula
  • Improved accuracy for deeply bound inner shell by introducing new gridding
  • Improvement of a model for the energy-loss spreading at b =0 (output in lineshape.dat)
  • Inclusion of the BARKAS EFFECT for close non-Coulombic collisions
  • Possible direct selection of the projectile charge-state
  • Speed up of stopping cross-section calculations

CasP version 3.2 (April 2007)

  • Improved relativistic correction accounting now for the impact-parameter dependence.
  • New: projectile-electron loss (energy losses due to projectile ionization and excitation) option now also for compounds 
  • New MEIS energy-loss parameter output (in ASCII data file ’lineshape.dat’).

CasP version 3.1 (August 2004)

  • Implementation of extended Bragg’s additivity rule for compounds.
  • New solid/gas target selection.
  • Improved accuracy for the kernel integration in the case of K shells of very heavy atoms such as Uranium.

CasP version 3.0 (April 2004)

  • Improved low-energy behavior due to new SHELL CORRECTION option.
  • Improved accuracy for deeply bound inner shells.

CasP version 2.2 (March 2004)

  • Slightly improved fit formulas with shell effects for projectile charge-states in gases (uncertainty is now reduced from dq = 0.48 to 0.46 charge units and from 2.6% to 2.3%)
  • Improved accuracy for CHARGE-STATE SCAN option (depends now on accuracy parameter) and, thanks to H.Paul, bug for light ions (H, He) is removed

CasP version 2.1 (December 2003)

  • New projectile-electron loss (energy losses due to projectile ionization and excitation) option
  • Improved fit formulas with shell effects for projectile charge-states in solids (uncertainty is now reduced from dq = 0.54 to 0.28 charge units and from 2.3% to 1.6%)
  • Improved accuracy for CHARGE-STATE SCAN option
  • Improved periodic table for projectile/target selection

CasP version 1.2 (October 2001)

  • New projectile charge-state and screening options:
    CHARGE-STATE SCAN for equilibrium energy losses
    GENERAL projectile screening for non-equilibrium energy losses (scaled DHFS potential)
  • Minor changes for output and data storage (STORE electron density)

CasP version 1.1 (October 2000)

  • Improved mean-charge-state formulas for gases and solids
  • Minor changes for input and data display

CasP version 1.0 (March 2000)

  • The first public (bug free?) version of the program.
