Density distribution of Li8 and 8B and capture reaction at low energy

G. W. Fan, Mitsuhiro Fukuda, D. Nishimura, X. L. Cai et autres

Reaction cross sections of $^{8}\mathrm{Li}$ on stable targets were measured at intermediate energies. With the existing experimental data of interaction cross sections at 790 MeV/nucleon the nucleon density distribution of $^{8}\mathrm{Li}$ was extracted by the use of the modified Glauber model. Meanwhile, …

Structure of Li8 from a reaction cross-section measurement

G. W. Fan, Mitsuhiro Fukuda, D. Nishimura, X. L. Cai et autres

We have precisely measured reaction cross sections (${\ensuremath{\sigma}}_{R}$) for $^{8}\mathrm{Li}$ using $^{9}\mathrm{Be}$, ${}^{12}\mathrm{C}$, $^{27}\mathrm{Al}$, and proton targets at intermediate energies by the transmission method. From the energy dependence of the ${\ensuremath{\sigma}}_{R}$ including the high energy data, the density distribution of $^{8}\mathrm{Li}$ was …

Charge-changing cross sections of Ne30 , Na32,33 with a proton target

Akira Ozawa, T. Moriguchi, T. Ohtsubo, N. Aoi et autres

The total charge-changing, charge pick-up, and partial charge-changing cross sections of very neutron-rich nuclei ($^{30}\mathrm{Ne}$, $^{32,33}\mathrm{Na}$) with a proton target have been measured at \ensuremath{\sim}240$A$ MeV for the first time. We introduced the phenomenological correction factor in Glauber-model calculations for the total …

Measurements of interaction cross sections for22–35Na isotopes

Shinji Suzuki, M. Takechi, T. Ohtsubo, D. Nishimura et autres

Interaction cross sections (σI) for 22−35Na isotopes from the stability line to the vicinity of the neutron drip line have been measured at around 240 MeV/nucleon. The σI for 33−35Na were measured for the first time. Enhancement in cross sections is clearly …

Charge-changing interactions probing point-proton radii of nuclei

Satoru Yamaki, J. Kouno, D. Nishimura, Masayuki NAGASHIMA et autres

The question of whether charge-changing interactions can be used to probe point-proton radii of nuclei remains unanswered. Charge-changing cross sections, σcc, were systematically investigated using stable and unstable nuclear beams of intermediateenergy. The ratios of the experimental σcc values to the calculated …

Density distributions of 11 Li deduced from reaction cross-section measurements

T. Moriguchi, Akira Ozawa, S. Ishimoto, Yasuaki ABE et autres

We measured the reaction cross sections of the two-neutron halo nucleus ${}^{11}$Li with solid hydrogen and carbon targets at around 31 and 41 MeV/nucleon. The neutron density distribution of ${}^{11}$Li was deduced for the first time by the Glauber model calculation based …

Measurements of α-decay half-lives at GSI

C. Nociforo, F. Farinon, A. Musumarra, F. Bosch et autres

One of the major problems in nuclear astrophysics concerns the estimation of electron screening effects on nuclear reaction rates. We have proposed investigating the electron screening effects of nuclear systems which decay via α-particles, using fragmented beams at relativistic energies produced at …

Hindered Proton Collectivity in S121628 : Possible Magic Number at Z=16

Y. Togano, Y. Yamada, N. Iwasa, Kazunari Yamada et autres

The reduced transition probability $B(E2;{0}_{gs}^{+}\ensuremath{\rightarrow}{2}_{1}^{+})$ for $^{28}\mathrm{S}$ was obtained experimentally using Coulomb excitation at $53\text{ }\text{ }\mathrm{MeV}/\mathrm{nucleon}$. The resultant $B(E2)$ value $181(31)\text{ }\text{ }{e}^{2}{\mathrm{fm}}^{4}$ is smaller than the expectation based on empirical $B(E2)$ systematics. The double ratio $|{M}_{n}/{M}_{p}|/(N/Z)$ of the ${0}_{gs}^{+}\ensuremath{\rightarrow}{2}_{1}^{+}$ transition …
