Measuring the Neutron’s Mean Square Charge Radius Using Neutron Interferometry
The neutron is electrically neutral, but its substructure consists of charged quarks so it may have an internal charge distribution. In fact it is known to have a negative mean square charge radius (MSCR), the second moment of the radial charge density. In other words the neutron has a positive core and negative skin. In the first Born approximation the neutron MSCR can be simply related to the...
متن کاملNuclear charge radius of 8He.
The root-mean-square (rms) nuclear charge radius of 8He, the most neutron-rich of all particle-stable nuclei, has been determined for the first time to be 1.93(3) fm. In addition, the rms charge radius of 6He was measured to be 2.068(11) fm, in excellent agreement with a previous result. The significant reduction in charge radius from 6He to 8He is an indication of the change in the correlation...
متن کاملLaser spectroscopic determination of the 6He nuclear charge radius.
We have performed precision laser spectroscopy on individual 6He (t(1/2)=0.8 s) atoms confined and cooled in a magneto-optical trap, and measured the isotope shift between 6He and 4He to be 43 194.772+/-0.056 MHz for the 2(3)S1-3(3)P2 transition. Based on this measurement and atomic theory, the nuclear charge radius of 6He is determined for the first time in a method independent of nuclear mode...
متن کاملBivariate mean value interpolation on circles of the same radius
We consider bivariate mean-value interpolationproblem, where the integrals over circles are interpolation data. In this case the problem is described over circles of the same radius and with centers are on astraight line and it is shown that in this case the interpolation is not correct.
متن کاملJa n 19 94 Simple Formula for Nuclear Charge Radius ∗
A new formula for the nuclear charge radius is proposed, dependent on the mass number A and neutron excess N−Z in the nucleus. It is simple and it reproduces all the experimentally available mean square radii and their isotopic shifts of even–even nuclei much better than other frequently used relations. PACS: 21.10.Dr, 21.60.Ev ∗This work is partly supported by the Polish Committee of Scientifi...
