Electrons are accelerated through a potential difference \V and protons are accelerated through a potential difference 4 {\V}. The de - Broglie wavelengths are \\lambda_{{e}} and \\lambda_{{p}} for electrons and protons respectively. The ratio of {\\lambda_{e}}/{\\lambda_{p}} is given by: (given m_{e} is mass of electron and m_{p} is mass of proton).
