Charge radii of C, N and O determined from their charge-changing cross-sections and the mirror-difference charge radii

J. W. Zhao, B. -H. Sun, I. Tanihata +24

Charge-changing cross-sections of C, N and O on a carbon target have been determined at energies around 300 MeV/nucleon. A nucleon separation energy-d…

Isospin-dependence of the charge-changing cross-section shaped by the charged-particle evaporation process

J. W. Zhao, B. -H. Sun, I. Tanihata +26

We present the charge-changing cross sections (CCCS) of C, N, and O at around 300 MeV/nucleon on a carbon target, which extends to -shell isotop…

Fundamental Neutron Physics: a White Paper on Progress and Prospects in the US

R. Alarcon, A. Aleksandrova, S. Baeßler +88

Fundamental neutron physics, combining precision measurements and theory, probes particle physics at short range with reach well beyond the highest energies probed by the LHC. Sign…

Fill and dump measurement of the neutron lifetime using an asymmetric magneto-gravitational trap

C. Cude-Woods, F. M. Gonzalez, E. M. Fries +39

The past two decades have yielded several new measurements and reanalyses of older measurements of the neutron lifetime. These have led to a 4.4 standard deviation discrepancy betw…

Improved neutron lifetime measurement with UCN

F. M. Gonzalez, E. M. Fries, C. Cude-Woods +41

We report an improved measurement of the free neutron lifetime using the UCN apparatus at the Los Alamos Neutron Science Center. We counted a total of approximately $38\…

Improved limits on Fierz Interference using asymmetry measurements from the UCNA experiment

Xuan Sun, E. Adamek, B. Allgeier +56

The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the -decay asymmetry parameter, , for free neutron decay. In the experiment, polarized ultracold n…
