Charge Pickup Reaction Cross Section for Neutron-Rich p -Shell Isotopes at 900 A MeV

B. Sun, I. Tanihata, S. Terashima, Feng Wang et autres

We report charge pickup reaction cross sections for 24 p -shell isotopes, including Li 8 , 9 , Be 10 − 12 , B 10 , 13 − 15 , C 12 , 14 − 19 , and N 14 , 15 …

Proton Distribution Radii of O 16 – 24 : Signatures of New Shell Closures and Neutron Skin

S. Kaur, R. Kanungo, W. Horiuchi, G. Hagen et autres

The root mean square radii of the proton density distribution in ^{16-24}O derived from measurements of charge changing cross sections with a carbon target at ∼900A MeV together with the matter radii portray thick neutron skin for ^{22-24}O despite ^{22,24}O being doubly …

Two-Neutron Halo is Unveiled in F 29

S. Bagchi, R. Kanungo, Y. Tanaka, H. Geißel et autres

We report the measurement of reaction cross sections (σ_{R}^{ex}) of ^{27,29}F with a carbon target at RIKEN. The unexpectedly large σ_{R}^{ex} and derived matter radius identify ^{29}F as the heaviest two-neutron Borromean halo to date. The halo is attributed to neutrons occupying …

Observation of excited states in Mg20 sheds light on nuclear forces and shell evolution

J.S. Randhawa, R. Kanungo, M. Holl, J. D. Holt et autres

The exotic Borromean nucleus $^{20}\mathrm{Mg}$ with $N=8$, located at the proton drip line provides a unique testing ground for nuclear forces and the evolution of shell structure in the neutron-deficient region. We report on the first observation of proton unbound resonances together …

Neutron skin and signature of the N = 14 shell gap found from measured proton radii of 17−22N

S. Bagchi, R. Kanungo, W. Horiuchi, G. Hagen et autres

A thick neutron skin emerges from the first determination of root mean square radii of the proton distributions for 17−22 N from charge changing cross section measurements around 900 A MeV at GSI. Neutron halo effects are signalled for 22 N from …

Halo-induced large enhancement of soft dipole excitation of 11 Li observed via proton inelastic scattering

Junki Tanaka, R. Kanungo, M. Alcorta, N. Aoi et autres

Proton inelastic scattering off a neutron halo nucleus, 11Li, has been studied in inverse kinematics at the IRIS facility at TRIUMF. The aim was to establish a soft dipole resonance and to obtain its dipole strength. Using a high quality 66 MeV …

Gsh ‐ 1 : A novel murine homeobox gene expressed in the central nervous system

M. Todd Valerius, Hung Li, Jeffrey L. Stock, Michael Weinstein et autres

We report the characterization of Gsh-1, a novel murine homeobox gene. Northern blot analysis revealed a transcript of approximately 2 kb in size present at embryonic days 10.5, 11.5, and 12.5 of development. The cDNA sequence encoded a proline rich motif, a …

Dominant mutation of the murine Hox‐2.2 gene results in developmental abnormalities

S. Kaur, Gurparkash Singh, Jeffrey L. Stock, Claire M. Schreiner et autres

Genes carrying the homeobox were originally identified in Drosophila, in which they are now known to play key roles in establishing segmentation patterns and in determining segment identities. A number of genes with striking homology to the Drosophila homeobox genes have now …
