The characteristic parameters of the reference particle are
defined by the command:
6 R(EFERENCE) P(ARTICLE)
<energy K in MeV>
<rest mass m00 in atomic mass units,
i.e. 1/12 of a 12C>
<charge
in charge units e,
where -e is the charge of one electron> ;
[example: R P 100 4 1 ;]
[R P 1 1 1 ;]
The charge of the particle is always assumed to be positive.
