A cryogenic apparatus is described that enables a new experiment, nEDM@SNS, with a major improvement in sensitivity compared to the existing limit in the search for a neutron Electric Dipole Moment (EDM). It uses superfluid $^4$He to produce a high d

Oklo reactors and implications for nuclear science

Autor: Davis, E. D., Gould, C. R., Sharapov, E. I.

Publikováno v: IJMPE 23, 1430007 (2014)

We summarize the nuclear physics interests in the Oklo natural nuclear reactors, focusing particularly on developments over the past two decades. Modeling of the reactors has become increasingly sophisticated, employing Monte Carlo simulations with r

La138/139 Isotopic Data and Neutron Fluences for Oklo RZ10 Reactor

Autor: Gould, C. R., Sharapov, E. I.

Publikováno v: Physical Review C86 027601 (2012)

Recent years have seen a renewed interest in the Oklo phenomenon, particularly in relation to the study of time variation of the fine structure constant. The neutron fluence is one of the crucial parameters for Oklo reactors. Several approaches to it

Search for the Neutron Electric Dipole Moment: Contributions from the Triangle Universities Nuclear Laboratory

Autor: Huffman, P. R., Golub, R., Gould, C. R, Haase, D. G., Kendellen, D. P., Korobkina, E., Swank, C. M., Young, A. R., Ahmed, M. W., Busch, M., Gao, H., Zhang, Y., Zheng, W. Z., Ye, Q.

A significant fraction of the research effort at the Triangle Universities Nuclear Laboratory (TUNL) focuses on weak interaction studies and searches for physics beyond the Standard Model. One major effort is the development of a new experimental tec

Time-variability of alpha from realistic models of Oklo reactors

Autor: Gould, C. R., Sharapov, E. I., Lamoreaux, S. K.

Publikováno v: Phys.Rev.C74:024607,2006

We reanalyze Oklo $^{149}$Sm data using realistic models of the natural nuclear reactors. Disagreements among recent Oklo determinations of the time evolution of $\alpha$, the electromagnetic fine structure constant, are shown to be due to different
