摘要: Abstract A dissatisfactory correlation results between beam widths obtained in electron and molecule diffraction experiments coherence length values calculated by the consequent use of some pertinent formulae. Arguments are presented for necessity to emphasize that patterns ultimately produced interference each particle with itself. These lead definition a on surface, which, analogy transfer width introduced Park et al., characterizes obscuring effect instrument. Formulae molecular compared experimental results.
