I attempted the following:

W = W(kin) = 350keV

now

[tex]W(kin)= (1-gamma)mc^2 [/tex]

so, now one could solve for gamma and find the velocity of the particle.

afterwards [tex] p=m*v=h/lambda [/tex]

HOWEVER: I get a negative result in a root when I try to solve for v. Therefore I think that my energy formula must be wrong (I already excluded calculation errors). Can anyone see it?
