Highly energetic electrons are bombarded
WebAt the operating ionizing energy of the analytical mass spectrometer (60–100 eV), the sensitivity of negative ion formation is several orders of magnitude less than that for positive ion production. If a neutral molecule is bombarded with electrons of increasing energy a sharp peak in ion production is observed between 0 and 10 eV. The energy ... WebNov 2, 2024 · Highly energetic electrons emit electromagnetic radiation, such as X-rays, when they hit solid matter – making them lose energy and get stuck in the target material.
