_R^2/4]}.    \label{ren}$$ Here $J$ is the spin of the resonance, $s_i$ are the spins of “incident particles”. We have used the number of partonic scatterers $\nu $ within a single nucleon volume $4\pi /3\mu ^3$ with $\mu $ the pion mass. For $n=3$, its estimated value $\nu \approx 20$ given above follows from Eq. (\[ren\]). Let us note that the similar expressions are widely used in optics, in particular, for defining the variety and abundance of chemical elements in the sun atmosphere (e.g., see [@9]).

Another information can be obtained from the height of the peaks in Fig. 1. It determines the width of the Cherenkov ring $\delta $. This is the ring in the plane perpendicular to the cone axis filled by evenly distributed within it particles over the smooth background due to jet fragmentation. Its projection on the diameter corresponds to the particle distribution which has a minimum at the center, increases, reaches the maximum at the internal radius of the ring $r_i$ and then decreases to zero at its external radius $r_e$. For narrow rings ($\delta \ll r_i$) the height of the maximum over the minimum is easily determined as $$h_{max}=\sqrt {2r_i\delta }-\delta .     \label{max}$$ With $h_{max}
