<div>Dear Gate users,</div>
<div><br>
</div>
<div>I've been running a simulation with an alpha surface source. The simulation runs smoothly, no errors or warnings and the results seem reasonable</div>
<div><br>
</div>
<div>Still, I have a limited experience simulating alpha particles and want to make sure that I use the correct physics list. </div>
<div><br>
</div>
<div>I would greatly appreciate if someone with experience of simulating alpha particles could look at the physics list below and see if something is missing. </div>
<div><br>
</div>
<div>Best regards</div>
