    Calculating particle velocity along crystal direction

    Yes, Zr is hexagonal. So I can use the (110) as my direction instead of converting it into x,y and z.

    Calculating particle velocity along crystal direction

    Okay, I'll give that a go. What do you mean by scaling the length to the required value?

    Calculating particle velocity along crystal direction

    It's the [1,1,2bar,0]. I wasn't sure if you could resolve the velocity using the basis vectors? If so, how do you resolve the original V into Vx etc? Is it V * cos (pi/2) = Vx?

    Calculating particle velocity along crystal direction

    Ahh okay. I looked it up and the equivalent of [11bar20] is [110] but I'm not sure how to convert this into equivalent Vx, Vy and Vz values if my V is 1107ang/ps ? i.e. what kind of angles or conversions do I need to do so that vx^2+vy^2+vz^2 = V ? Thanks in advance

    Calculating particle velocity along crystal direction

    I am currently looking at setting up a particle, with energy 5keV, traveling along the [11bar2 0] direction in Zr but I am struggling to get my head around how to resolve the velocity into the 3 directions to make sure it travels along this specific crystal direction. Could anyone help point...

    Exponential of a large negative number

    Hi, I read on a previous post that to calculate the exponential of a large negative number I use the formula: e-r=10(-rloge) This is just a quick question but it it meant to be a log 10 or natural log and also is it meant to be loge0 or loge1 Thanks in advance

    Calculate PKA Velocity in 10keV Fe Collision

    [QUOdoesn't say b, post: 5008341, member: 405866"]10 keV and 262km/s lead to A=28, something like silicon. Iron at that energy would be slower. What is your primary particle that collides with the material? It doesn't say what incident particle it is although I would assume a neutron. Although...

    Calculate PKA Velocity in 10keV Fe Collision

    Hi, I've been trying to understand a simulation for a collision cascade. The PhD that produced this code says that he is modelling a 10keV collision in Fe. From this he says that his PKA velocity is 2620.579 ang/ps or 262057.9 m/s and I'm wondering how did he get this? I've assumed that the...
