N2 - Mathematical methods are developed to describe helium sorption by microspheres with a certain size distribution. An analytical solution of the problem is derived and applied to expand the experimental dependences of the degree of helium sorption by microspheres on time into harmonics. As a result, the time characteristics of the sorption process can be analyzed.
