Question delta-rays track of DNA-Physics and Livermore-Physics  

Forum: DNA/Very Low Energy
Date: 06 Sep, 2016
From: Batom <Batom>

Dear Experts,

I compared the track structure of 600 MeV/u Iron ion in 200 um box for three physics processes of DNA-Physics, Livermore-Physics and Standard-Physics. In the case of DNA-Physics, secondary electrons should be travel long distance from track core of energetic Iron ions. But, I does not see delta-rays like Livermore and Standard physics. I have some questions:

1. Please explain that why does not travel away delta-rays from track core of Iron particle at DNA-Physics? 2. Have a cut-value of high energy electrons for DNA-Physics? How (or possible) to obtain track structure of Iron ions in few hundred micrometer by DNA-Physics like Livermore-Physics (with energetic delta-rays)?

3. My some results of DNA and Livermore physics are so different: In the case of Livermore and Standart physics, probability of particle hits is increasing with increase LET. Contrariwise, probability of particle hits is decreasing with increase LET for DNA-Physics. Here, values of LET are higher than 100 keV/um. I just wordering that probability why decrease for DNA-Physics? If its true, I need to some explination.

Results attached in follow.

Thank you for your advise! Best Regards, Batom.
