Dear Yang,
1) Continuous energy loss goes along the track (SUBROUTINE MGDRAW),
energy deposition on the spot (ENTRY ENDRAW). You will a lot of energy
deposition events on the track, see attachment.
2) Lithium is heavier than alpha particle, and its energy is less.
I have changes some elements in attachment.
Best regards,
Mikhail
