Based on a United Press International dispatch, an item in the Monitor's 0ct. 20 issue incorrectly stated that the Nobel Physics Prize was awarded for research in the use of lasers to enrich uranium for atomic bombs. The award was given for discoveries in laser spectroscopy - a technology that helps in understanding the properties of atoms and molecules. The technology was discovered by the prizewinners - Nicolaas Bloembergen, Arthur Schawlow, and Kaie Siegbahn - and it is possible it could be applied to atomic bomb development, one of the Nobel recipients said. But the prize was awarded for the laser discoveries. Those advances have been applied by other scientists primarily in communications technology. The Monitor regrets the error.
