Abstract
IT has recently been reported by Daniel et al.1 that in high-energy collisions between nucleons, besides π-mesons, some heavier mesons of about 1,300 me mass are also created. The purpose of the present note is to estimate the theoretical probability of emission of a heavy meson in a collision process, using the statistical theory developed by Fermi2. The collision is studied in the centre-of-mass system of the particles and it is assumed that the total energy W (W is the energy in the centre-of-mass system) is suddenly released in a small volume, surrounding the nucleons (M = mass of the nucleon, μ = mass of π-meson). One then calculates statiscally the probability that a certain number of mesons are created.
