Times Cited Count:0 Percentile:0.00(Chemistry, Physical)The Alder-ene reaction is a chemical reaction between an alkene with an allylic hydrogen, and it provides an efficient method to construct the C-C bond. Traditionally, this reaction requires catalysts, high temperatures, or photocatalysis. In this study, we reported a high-pressure-induced solid-state Alder-ene reaction of 1-hexene at room temperature without a catalyst. 1-Hexene crystallizes at 4.3 GPa and polymerizes at 18 GPa, forming olefins. By exploring gas chromatography-mass spectrometry, we discovered that 1-hexene generates dimeric products through the Alder-ene reaction under high pressures. The in situ neutron diffraction shows that the reaction process did not obey the topochemical rule. A six-membered ring transition state including one C-H bond and two alkene
bonds was evidenced by the theoretical calculation, whose energy obviously decreased when compressed to 20 GPa. Our work offers a novel and promising method to realize the Alder-ene reaction at room temperature without a catalyst, expanding the application of this important reaction.

) reaction. The triple differential cross-section was extracted and compared to distorted-wave impulse approximation reaction calculations performed in a microscopic framework using the Tohsaki-Horiuchi-Schuck-R
pke wave function and the wave function deduced from Antisymmetrized Molecular Dynamics calculations. The remarkable agreement between calculated and measured cross-sections in both shape and magnitude validates the description of the
Be ground-state as a rather compact nuclear molecule.

Times Cited Count:13 Percentile:87.42(Physics, Multidisciplinary)We report on the first proton-induced single proton- and neutron-removal reactions from the neutron deficient O nucleus with large Fermi-surface asymmetry at
100 MeV/nucleon. Our results provide the first quantitative contributions of multiple reaction mechanisms including the quasifree knockout, inelastic scattering, and nucleon transfer processes. It is shown that the inelastic scattering and nucleon transfer, usually neglected at such energy regime, contribute about 50% and 30% to the loosely bound proton and deeply bound neutron removal, respectively.

Anion-exchange behavior of the group-6 elements, W and Mo, in HF and HNO mixed solutions has been studied by a batch method using the carrier-free radiotracers
W and
Mo. The long-lived isotope
W and the short-lived isotope
Mo were produced in the
Ta(p,n) and the
Nb(p,n) reaction at the JAEA tandem accelerator, respectively. The solutions containing
W or
Mo were mixed with anion exchange resin. Radioactivities of the solution were assayed for
-ray spectrometry, and then distribution coefficients (K
s) of these elements were determined. It was found that the K
values of W depend strongly on the concentration of HF, while those of Mo are almost constant as a function of [HF] under the given conditions.

Cation-exchange behavior of Rf (T

Cm(
O,5n) reaction was studied on a "one-atom-at-a-time" scale in 0.15-0.69 M H
SO
/HNO
mixed solutions ([H
] = 1.0 M) using an automated ion-exchange separation apparatus coupled with a detection system for alpha-spectroscopy (AIDA). It was found that adsorption probabilities (%ads) of Rf on the cation-exchange resin decrease with increasing [HSO
], showing successive formation of Rf sulfate complexes. Rf exhibits a weaker complex formation than the lighter homologues Zr and Hf.
