A particle picture of “tunneling” and the nature of “photon”-matter interaction

Brownian motion is employed as a model to formulate a probabilistic statement of the Heisenberg uncertainty relationship. By means of the latter, a tunneling formula identical to that obtained from the WBK method is derived from the particle picture. The nature of photon-matter interaction is discussed in the light of the quantal Brownian motion.Research supported under NSF Grant #GP-12408.Contribution No. 3080 from the Department of Chemistry, University of California, Los Angeles, California.Currently on sabbatical leave from the University of Missouri-Columbia.
