The study of the distribution of energy that is lost by scattered electrons when a substance is bombarded with monochromatic electrons.2. A technique for studying atoms, solids, or molecules in which a substance is bombarded with monochromatic electrons, and the energies of scattered electrons are measured to determine the distribution of energy loss.
2. The loss of energy by conversion to heat in a system exhibiting hysteresis.
Hysteresis loss in a magnetic circuit is the energy expended to magnetize and demagnetize the core.
Methods of preserving foods add to the loss of vitamins. Pickling, salting, curing, or fermenting processes usually cause complete loss of vitamin C.
Commercial canning destroys frokm 50% to 85% of vitamin C contained in peas, lima beans, spinach, and asparagus. Pasteurization, unless special precautions are observed, causes a loss of from 30% to 60% of the vitamin C.
