Re: error in t+Li reaction

Dear Andrzej,

the crash occurs at the inizialization stage and concerns the stopping
power calculation, due to the quite high density value you input for your
lithium compound (7g/cm^3?!). In fact, error messages about the
Sternheimer's parameters of the density effect term appear as well.

Note that, if DEUT-LIT is intended to be a compound of Li6 and Li7, the
definitions of LITHIU-6 and LITHIU-7 are wrong, since they do not identify
single isotope elements. In order to do this, as already mentioned a few
times (e.g., see the last one at,
you have to specify the *mass number* (6.0 or 7.0) in the WHAT(6) of the
MATERIAL card. The WHAT(2)field requires instead, at the same time, the
*atomic mass* in amu, which, e.g., for Li7 is not 7.0 but 7.016.

Moreover, requesting the old evaporation model (PHYSICS card with
SDUM=EVAPORAT and WHAT(1)=1.0) is not allowed and will imply a run stop.

Best wishes for a tasty 2010 to everybody
