Simple formula for nuclear charge radius

Ja 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...

Nuclear 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...

Laser 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...

Calculating charge radius for proton with hyper central interacting color potential

An improved M.I.T. bag model with hyper central interaction is used to calculate the charge radius for proton containing u and d quarks. We present a theoretical approach to the internal structure of three-body hyper central interacting quarks in a proton, in which we take proton as a bag. We discuss a few of results obtained using a six-dimension potential, which is attractive for small separa...
