6th China-Japan Joint Nuclear Physics Symposium

Angular distribution of the cross sections of the elastic He-transfer of the He nucleus on the Be target were measured at the incident energy of 25 MeV/nucleon.The experimental data at the backward angles were analyzed within the finite-range DWBA framework.A large spectroscopic amplitude of 1.41 for the He-cluster in the ground state of the Be nucleus was needed for this experiment,which is much larger than its theoretical prediction of 0.286.

The differential cross sections of quasielastic scattering of a 25MeV/u 6He from 9Be target have been measured. The double-folding model approach is applied to generate the real part of the optical potential. The imaginary potential parameters as well as some of the real potential parameters are studied in comparison with the experimental data. The effect of the unstable nucleus is discussed.

The internal structure of the lightest halo nucleus He is one of the most interesting subjects in recent rNB Physics study [1]. We report here the experimental results of the In and 2n transfers in the reaction of He +Be at 25MeV/u. The experiment was performed at rIKEN in Japan with the rIPS beam line. The 25MeV/u He beam was produced and purified from the projectile fragmentation of 70MeV/u C primary

Background Africa sees the surge of plague cases in recent decades,with hotspots in the Democratic republic of Congo,Madagascar,and Peru.A rodent-borne scourge,the bacterial infection known as plague is transmitted to humans via the sneaky bites of fleas,caused by Yersinia pestis.Bubonic plague has a case fatality rate of 20.8%with treatment,but in places such as Madagascar the mortality rate can increase to 40–70%without treatment.Main text Tragedy strikes in the Ambohidratrimo district as three lives are claimed by the plague outbreak and three more fight for survival in the hospitals,including one man in critical condition,from the Ambohimiadana,Antsaharasty,and Ampanotokana communes,bringing the total plague victims in the area to a grim to five.Presently,the biggest concern is the potential plague spread among humans during the ongoing COVID-19 pandemic.Effective disease control can be achieved through training and empowering local leaders and healthcare providers in rural areas,implementing strategies to reduce human–rodent interactions,promoting water,sanitation and hygiene practices(WASH)practices,and carrying out robust vector,reservoir and pest control,diversified animal surveillance along with human surveillance should be done to more extensively to fill the lacunae of knowledge regarding the animal to human transmission.The lack of diagnostic laboratories equipped represents a major hurdle in the early detection of plague in rural areas.To effectively combat plague,these tests must be made more widely available.Additionally,raising awareness among the general population through various means such as campaigns,posters and social media about the signs,symptoms,prevention,and infection control during funerals would greatly decrease the number of cases.Furthermore,healthcare professionals should be trained on the latest methods of identifying cases,controlling infections and protecting themselves from the disease.Conclusions Despite being endemic to Madagascar,the outbreak’s pace is unparalleled,and it ma

The inclusive differential cross sections of the 7Li nucleus in a reaction induced by 6He on a 9Be target are measured at an incident energy of 25MeV/nucleon. Finite-range distorted-wave Born approximation calculations suggest that these 7Li particles are formed in a direct single-proton pickup reaction 9Be(6He,7Li)8Li. The experimental data can be well reproduced by taking into account of the contributions of both the ground states and the first excited states of 7Li and 8Li.
