Atomic Masses, Q-values, and Threshold Energies

This Q-value calculation program allows you to calculate reaction Q-values and threshold energies and decay Q values based on the 1995 Update to the Atomic Mass Evaluation and to retrieve other quantities contained in this evaluation. 2003 atomic mass evaluation, NUBASE, PC-NUCLEUS. The program QCALC has been produced by the National Nuclear Data Center of the Brookhaven National Laboratory, Upton, NY, USA, with funding from the U.S. Department of Energy.
The accompanying data base was produced by the Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse, Orsay Campus, France and the National Institute of Nuclear Physics and High-Energy Physics, Amsterdam, The Netherlands.
