0163 <H2>6. Items for migration of the user code</H2>
0164
0165 Some migrations may be necessary for advanced uses of features in Geant4
0166 in order to upgrade from release 8.0 to release 8.1. Note that a full reinstallation
0167 of libraries (or a full recompilation) and a recompilation of user applications
0168 is required.
0169
0170 <P> </P>
0171 <B>Standard Electromagnetic physics</B>
0172 <P> </P>
0173 Some improvements are introduced to multiple scattering.
0174 As a consequence of these changes in the model, the following applies in
0175 this release:
0176 <UL>
0177 <LI>the simulation of the back-scattering is improved;</LI>
0178 <LI>the scattering in very thin layers is better than the one in version 8.0;</LI>
0179 <LI>the tail of the angular distribution is now material dependent;</LI>
0180 <LI>the visible energy in sampling calorimeters is less sensitive
0181 to the value of the production threshold.</LI>
0182 </UL>
0183 It has been reintroduced the option to utilise smaller cuts in vicinity of
0184 the geometrical boundary. The <I>subcutoff</I> option has been verified for
0185 a number of simplified sampling calorimeter setups.
0186 The simulation of ionization for ions was also improved. The data from NIST
0187 databases for protons and helium ion and ICRU73 data for the carbon ion are
0188 included for the first time. An interface to add user data on stopping
0189 power for particular ion in particular media is provided.<BR>
0190 A new version of the Synchrotron radiation is released.<BR>
0191 The user interfaces allowing to set/access EM options, cross sections and
0192 stopping powers are extended and improved.
0193
0194 <P> </P>
0195 <B>Hadronic physics: Bertini Cascade</B>
0196 <P> </P>
0197 In this release, the <TT>G4BERTINI_KAON</TT> conditional assembly flag has
0198 been removed from the Bertini Cascade code, so that it is no longer needed
0199 for the user to set them to instruct Bertini handling of strange particles.
0200
0201 <P> </P>
0202 <B>Physics Lists</B>
0203 <P> </P>
0204 Physics lists are updated in order to utilize recent developments
0205 in hadronic and electromagnetic physics. In particular, the more advanced
0206 model sampling of capture of negatively charged hadrons at rest is used.
0207 The new elastic process combining available models of elastic scattering
0208 is introduced with significant improvement of elastic scattering on
0209 hydrogen; the Binary and Bertini cascade developments are also utilized.
