Probing isoscalar giant resonances with multipolarity L ≤ 3 in even- A neodymium isotopes

M. Abdullah, K. Khokhar, S. Bagchi, Muhsin N. Harakeh et autres

Background-free inelastic-scattering spectra were measured for even-$A$ neodymium (Nd) isotopes using a halo-free 386-MeV $\ensuremath{\alpha}$ beam at forward angles, including ${0}^{\ensuremath{\circ}}$, to examine the influence of deformation on isoscalar giant resonances. The strength distributions of isoscalar giant resonances (with multipolarity $L\ensuremath{\le}3$) in …

Effect of ground-state deformation on the isoscalar giant monopole resonance and the first observation of overtones of the isoscalar giant quadrupole resonance in rare-Earth Nd isotopes

M.N.A. Abdullah, S. Bagchi, Muhsin N. Harakeh, H. Akimune et autres

The strength distributions of the Isoscalar Giant Monopole Resonance (ISGMR) and Isoscalar Giant Quadrupole Resonance (ISGQR) in 142,146−150Nd have been determined via inelastic α-particle scattering with the Grand Raiden (GR) Spectrometer at the Research Center for Nuclear Physics (RCNP), Japan. In the …

Precise Spectroscopy of the 3 n and 3 p Systems via the H 3 ( t , He 3 ) 3 n and He 3 ( He 3 , t ) 3 p Reactions at Intermediate Energies

K. Miki, K. Kameya, Daisuke Sakai, Ren Urayama et autres

To search for low-energy resonant structures in isospin T=3/2 three-body systems, we have performed the experiments ^{3}H(t,^{3}He)3n and ^{3}He(^{3}He,t)3p at intermediate energies. For the 3n experiment, we have newly developed a thick Ti-^{3}H target that has the largest tritium thickness among targets …

C 10 + α elastic scattering: A study of the proton-rich O 14 nucleus and α clustering

Nanru Ma, Michele Sferrazza, H. Yamaguchi, S. Okamoto et autres

The $^{10}\mathrm{C}+\ensuremath{\alpha}$ elastic cross section was measured to investigate the structure of the proton-rich $^{14}\mathrm{O}$ nucleus. A radioactive beam of $^{10}\mathrm{C}$ was produced at the RI beam separator CRIB using the $^{10}\mathrm{B}(p,n)^{10}\mathrm{C}$ reaction with a $^{10}\mathrm{B}$ beam energy of 6.99 MeV/nucleon.

Search for the 6α condensed state in 24Mg using the 12C+12C scattering

Y. Fujikawa, T. Kawabata, Satoshi Adachi, Shiyo Enyo et autres

We searched for the 6α-condensed state in 24Mg by measuring the C12+12C scattering with the SAKRA Si detector array at Ecm=17.5–25.0 MeV. By using the invariant-mass method for the detected 3α particles, the inclusive cross sections for the C12+12C→12C(02+)+X and C12(31−)+X reactions …

Masanori Takemoto, Y. Fujikawa, Kenta Iyoki, Nao Tsunoji et autres

Interzeolite conversion (IZC) of zeolites has attracted significant attention; however, research on silicoaluminophosphate zeolite system is still in its early stages. Herein, an IZC of an FAU-type silicoaluminophosphate zeolite (SAPO-37) is performed using tetramethylammonium hydroxide (TMAOH) and piperidine as organic additives. For …
