We prove that any non-negative function f on Gaussian space that is not too log-concave (namely, a function satisfying Hess(log(f)) > - C Id) has tails strictly better than those given by Markov's inequality:

P(f > c)
where E[f] denotes the (Gaussian) expectation of f. An immediate
consequence is a positive answer to the Gaussian variant of Talagrand's (1989) question about regularization of L^1 functions under the convolution semigroup.

An exact representation is presented for the field inside a sphere
(the observation sphere) due to primary sources enclosed by a second sphere
(the source sphere). The regions bounded by the two spheres have no common
points. The field of the primary sources is expressed in terms of Gaussian
beams whose branch-cut disks are centered in the source sphere. The
expansion coefficients for the standing spherical waves in the observation
sphere are expressed in terms of the output of Gaussian-beam receivers,
