i have found out that if i set the life state of the deuterium particles with a very large no. such as  99999999999999999 will cause a weird phenomenon which when the deuterium particles collides with other particles,it expands into many deuterium particles which some of them have a very high life state and turns into a deuterium particles with a low life state immediately and vanishs after that(and the neutron and protons also dont reacts with the deuterium immediately after colliding with the deuterium) but not expanding into many deuterium particles immediately after setting the life state of the deuterium particles.Is this normal?
