Find wavelength of pair producing photon

  1. Mar 24, 2009 #1
    1. The problem statement, all variables and given/known data


    i just have questions the one i couldn't figure it out

    the eletroc/position pair produce track drift chamber has field of 0.2 weber/m^2, radius of the drift 0.025m.

    using p = eBr equation to find the energy and wavelength of the pair producing photon.

    with the momentum i am be able to find the wavelength and energy, but i am confuse with the wavelength pair producing photon.

    any luck...
