About this Item

Druck auf Anfrage Neuware - Printed after ordering - The search for examples of proton radioactivity has resulted in the discovery of a large number of proton emitters in the region 50 Z 84 [1]. Many of these proton emitters and their daughters are also a-emitters, and in some cases the a-decay chain from the daughter terminates on a nuclide closer to stability whose mass excess is known. This opens up the possibility of using a-and proton-decay Q-values to determine the mass excesses of a large group of nuclei connected by particle decay. The Q-values are derived from the measured kinetic energies of the emitted protons or a-particles. Where the decay chains are not connected to nuclei with known mass excesses, proton separation energies can be measured in some cases and derived in others. For the a-decay ofthe parent nucleus (Z, A) to the daughter (Z - 2, A - 4), the energy and momentum relations used to convert between Q-value, mass (M) and mass excess (ME) are: M(4He)E', (1) M(Z - 2, A - 4)Erecoil, (2) Q', E', + Erecoi, ME(Z, A) Q', + ME(Z - 2, A - 4) + ME(4He). (3) In practice, one uses M(4He) ~ 4 and M(Z - 2, A - 4) (A - 4), so that Equation (3) becomes ME(Z, A) = E', (_A_) + ME(Z - 2, A - 4) + ME(4He). (4) A -4 Similarly, for protons, we have ME(Z, A) = Ep(_A_) +ME(Z - 1, A-I) +ME(lH).

About this title

Synopsis

This volume is a comprehensive and up-to-date compendium of worldwide experimental programmes dedicated to the pursuit of atomic mass measurements. A tutorial section includes the various fields of physics in which atomic masses play an important role: nuclear physics, quantum electrodynamics, stellar nucleosynthesis, and weak interaction studies. There is a section devoted to theoretical approaches for both atomic and nuclear interactions, as well as a host of new projects for further advancing the field. This volume presents both an introduction and review of the state-of-the-art concerning mass measurements, evaluation, and prediction.
