The $$alpha$$-decay branching ratio of 0.52(5)% from the ground state of $$^{180}$$Pt to the ground state of the daughter nucleus $$^{176}$$Os has been determined more precisely than before. The $$^{180}$$Pt was produced as the $$beta$$-decay granddaughter of $$^{180}$$Hg which was produced and separated with the CERN-ISOLDE facility. The reduced $$alpha$$-decay width calculated with the present result has provided a new picture of the systematics for the $$alpha$$-decay width of neutron-deficient Pt isotopes.

The ENDF/B-VII.1 library is our latest recommended evaluated nuclear data file for use in nuclear science and technology applications, and incorporates advances made in the five years since the release of ENDF/B-VII.0. These advances focus on neutron cross sections, covariances, fission product yields and decay data, and represent work by the US Cross Section Evaluation Working Group (CSEWG) in nuclear data evaluation that utilizes developments in nuclear theory, modeling, simulation, and experiment. It features extension of covered nuclei, covariance data for 190 nuclei, R-matrix analyses of neutron reactions on light nuclei, updates for some medium-heavy and actinoid nuclei, etc. Criticality benchmark tests with a transport simulation code MCNP shows improved performances.

Visualization, analyis, and management of nuclear mass information at nucearmasses.org

Smith, M. S.*; Lingerfelt, E. J.*; Buckner, K.*; Nesaraja, C. D.*; Koura, Hiroyuki; Kondev, F.*

We have built the first and only online suite of codes that enables researchers to quickly and efficiently manage, visualize, access, manipulate, share, compare, and analyze nuclear masses. Our system, freely available at nuclearmasses.org, is a platform-independent client-server application that accommodates the latest mass measurements, theoretical models of nuclear masses, and large tables of evaluated nuclear masses. There is a strong need for this service, because of (1) the widespread utilization of nuclear masses in basic and applied science, (2) the tremendous growth in mass measurement capabilities, facilities, and new results, and (3) the inadequacy of existing systems that disseminate nuclear mass information. With our system, researchers can upload their own mass datasets, store them, share them with colleagues, and quickly and easily visualize them in customizable one- and two-dimensional plots.

The masses of exotic nuclei near the limits of stability play an important role in a wide variety of studies, such as simulations of r-process nucleosynthesis occurring in supernovae, determination of reaction cross sections of halo nuclei, and global models of the structure of nuclei. To handle this amount of mass information, we have built an online, dedicated suite of codes. Our system, freely available at nuclearmasses.org, is a platform-independent client-server application. With our system, researchers can upload their own mass datasets, store them, share them with colleagues, and quickly and easily visualize them in customizable one- and two-dimensional plots. Mass dataset analysis tools are also available, enabling the average RMS differences between a reference dataset and numerous other sets to be determined. We have recently added the capability to visualize the two-neutron separation energy surface. More analysis tools will be developed for our suite.

Nuclear masses form an essential ingredient in simulations of a variety of astrophysical environments and events -such as r-process nucleosynthesis in supernovae. While laboratory advances have led to a tremendous increase in the number and precision of new mass measurements, the dissemination of this information has many inadequacies. To address this impediment to progress, we have built an online, dedicated suite of codes that enables researchers to quickly and efficiently share, manage, visualize, access, manipulate, compare, and analyze nuclear mass datasets. Our system, available at nuclearmasses.org, is a platform-independent client-server application that accommodates the latest mass measurements, theoretical mass models, and large tables of evaluated nuclear masses. With our system, researchers can upload their own mass datasets, store them, share them with colleagues, quickly and easily visualize them in customizable 1D and 2D plots, and calculate and plot RMS differences.

The masses of nuclei play an important role in a wide variety of studies, such as simulations of r-process nucleosynthesis occurring in supernovae, global models of the structure of nuclei, and statistical model calculations of reaction cross sections. More, mass measurements are being made than ever before. To handle the substantial amount of new mass information, we have built an online suite of codes that enables researchers to quickly and efficiently visualize and analyze nuclear mass datasets. Our system is a platform-independent client-server application that accommodates the latest mass measurements and theoretical mass models. We have provided a first set of mass dataset analysis tools which can switch from 2d plots of masses to plots of separation energies. We have recently added the capability to visualize the two-neutron separation energy surface. The website hosting our code suite also provides an easy mechanism to inform the community of nuclear masses.

Nuclear masses are crucial in many areas of basic and applied nuclear science, ranging from r-process nucleosynthesis in supernovae to developing new models of superheavy nuclei. There is significant international effort in new mass measurements, new theoretical mass models, and new mass evaluations - but the dissemination of mass information has not kept pace with these important developments. We have built an online, dedicated suite of codes to address this problem - the ${bf Nuclear Mass Toolkit}$ at ${bf nuclearmasses.org}$. This free, platform-independent system enables researchers to quickly and efficiently share, manage, visualize, access, manipulate, compare, and analyze nuclear mass datasets. With our system, researchers can upload their own mass datasets, store them, share them with colleagues, quickly and easily visualize them in customizable 1D and 2D plots, and calculate and plot RMS differences. We will demonstrate the utility of our site by comparing the RMS deviations of a variety of different theoretical mass models from the AME2003 evaluated masses, over a variety of mass ranges.
