We present the results of new mass-spcttrographic measurements of the atomic masses of C 13 , N 14 and N 15 . We show the "internal consistency" for the mass values of these isotopes obtained from different sets of mass doublets. The measurements were performed under conditions climinating...

The comparison of experimental with calculated K-capture probabilities yielded the decay energies of 145 Sm and 151 Gd, Q EC =622(5) and 463(3) keV, respectively. Earlier discrepancies in the mass adjustment of these isotopes were removed and adjusted masses for 145 Sm, 145 Pm and 151 Gd...
Mass number, in nuclear physics, the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is commonly cited in distinguishing among the isotopes of an element, all of which have the same atomic number (number of p
Atomic Mass vs. Mass Number: Unravel the Mystery By Todd Helmenstine Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes. The atomic weight can change because it depends on our understanding of how much of each isotope of an...
