Abstract

The invention relates to a particle scattering demonstrating device which comprises a scattering table, an inclined rollaway nest, an electrified ball, an electrified body and a high potential table. The high potential table is arranged above the scattering table; one end of the inclined rollaway nest is connected to the high potential table while the other end is connected to the side portion of the upper surface of the scattering table, and the central line of the inclined rollaway nest penetrates through the center of the scattering table; the electrified ball is arranged on the high potential table and can tumble to the scattering table along the inclined rollaway nest; the electrified body is arranged in the bottom of the center of the scattering table; the electrified ball is a ball body with a positive charge or a negative charge; and the electrified body is a ball body or a cone body with a positive charge or a negative charge, and the shaft axis of the ball body or the cone body penetrates through the center of the scattering table. Based on Coulomb interactions, the particle scattering demonstrating device not only can demonstrate the scattering effect of rejecting interaction, but also can demonstrate the scattering effect of attracting interaction, so that the particle scattering phenomenon and principle can be intuitively demonstrated. The particle scattering process is demonstrated by means of the device, so that the atomic structure is learned.

Description

technical field [0001] The invention relates to the field of teaching demonstration devices, in particular to a particle scattering demonstration device. Background technique [0002] Particle scattering is an important verification experiment to understand the structure of atomic nucleus. Due to the limitation of experimental equipment, learning the structure of atomic nucleus can only demonstrate the process of particle scattering through models. At present, some particle scattering demonstration instruments use a cylindrical or conical shape to simulate the particle barrier, which is quite different from the Coulomb interaction in the real particle scattering experiment. The demonstration effect is not ideal, which is not conducive to helping understand the principle of particle scattering and understanding atoms. Structure. Contents of the invention [0003] In view of the unsatisfactory demonstration effect of the existing particle scattering demonstration apparatus ...
