EXPERIMENTS ATOMIC – NUCLEAR PHYSICS

•  Linear propagation of cathode rays / of electron beams •  Electrostatic charging effects •  Electron deflection by a magnetic field Straight-line propagation of electrons in the absence ... more

•  Introduction to electron optics Cathode rays and deflecting fields can be used to magnify shadow images in a manner analogous to an optical lens system. With the help of this supplement, the experiment: Maltese-Cross ... more

•  Observing the thermionic emission of charge-carriers from a heated cathode. •  Determining the polarity of the emitted charge-carriers. •  Estimating the specific charge (chargeto-mass ratio ... more

•  Investigate the deflection of an electron beam by a magnetic field. •  Investigate the deflection of an electron beam by an electric field. •  Construct a velocity filter using orthogonal electric ... more

Electrons in a fine-beam tube are deflected into a circular path by a uniform magnetic field. The tube contains neon gas at a precisely defined pressure so that gas atoms become ionised by collision with electrons along the path thus ... more

Objective: Record and interpret the Balmer series of lines for hydrogen other line spectra in the visible region The line spectra of light-emitting atoms are uniquely characteristic for each specific chemical element, although they become ... more

Objective: Demonstrate electron spin resonance in DPPH Electron spin resonance (ESR) is based on the energy absorption by substances with unpaired electrons, which are inside an external magnetic field produced by a DC source. The energy ... more

Objective: Demonstrate and compare nuclear magnetic resonance in glycerine, polystyrene and Teflon Nuclear magnetic resonance (NMR) is based on the energy absorption by substances with nuclear magnetism, which are inside an external magnetic ... more
