In the Breit-Pauli approximation, terms for a specific J value interact, and this requires that mixing effects between terms be considered. The traditional MCHF method was modified to permit a simultaneous optimization of the weighted energy expressions derived from multiple terms. This allowed a single orbital set to represent a choice of terms with strong relativistic mixing. Then, by diagonalization of the Breit-Pauli Hamiltonian a few selected eigenvalues were determined. The bi-orthonormal method was applied to compute the transition data.
Note to the system administrator of hf5: If problem occurs with the hf program on the Web, hf5 should be checked for the following:

If the Java server was not running the output would have been:

Both, the Apache server and the hf Java server are configured to automatically start upon rebooting of the node hf5. While the scripts for the Apache server are default in the RedHat 7.1 installation and have not been modified, the hf Java server startup script is executed in /etc/rc.local (this script starts the local services). /etc/rc.local starts the hf Java server by executing the script /var/www/html/sh_start_HFapplet_server. Note that in order to start the hf Java server it is sufficient to execute as a root:
#cd /var/www/html/ #./_start_HFapplet_server
The file /var/www/html/log.hf_applet keeps information about all IP's which had accessed the hf program and performed runs (The output below shows a portion of this file and IP's from all over the world for the last 2 months > 1000 accesses):
