Time-dependent Calculations for Two-proton Decay Width with Schematic Density-dependent Contact Pairing Interaction

原子核物理评论 2016年第2期33卷 203-206页

We calculate the two-proton decay width of the6 Be nucleus employing the schematic densitydependent contact potential for the proton-proton pairing interaction. The decay width is calculated with a time-dependent method, in which the two-proton emission is described as a time-evolution of a threebody meta-stable state. Model-dependence of the two-proton decay width has been shown by comparing the results obtained with the two different pairing models, schematic density-dependent contact and Minnesota interactions, which have zero and finite ranges, respectively.

Impact of Rotavirus Vaccination in Severe Rotavirus Gastroenteritis Outpatient Visits at Three Pediatric Primary Care Clinics in Shibata City, Niigata Prefecture, Japan

Open Journal of Pediatrics 2014年第4期4卷 291-299页

The impact of rotavirus (RV) vaccination in reducing severe rotavirus gastroenteritis (RVGE) in outpatient settings was prospectively surveyed in three pediatric clinics in Shibata City. In children younger than 3 years of age, the occurrence of severe RVGE among all acute gastroenteritis (AGE) was found to be significantly lower in three seasons after introduction of RV vaccines, compared to that in 2011, before introduction of RV vaccines. The incidence rates of severe RVGE among children younger than 3 years of age were found to be reduced by 71.2%, 47.7%, and 81.1% for 2012, 2013, and 2014, respectively, compared to that in 2011. These results suggest that the RV vaccination is effective for the prevention of severe RVGE in Japanese voluntary RV vaccination settings with estimated coverage rates of 32.5%, 40.5% and 47.1% for 2012, 2013 and 2014, respectively. It is expected that the reducing effect on severe RVGE would be persistently established by increasing the vaccine coverage rates.

We simultaneously observed both the fast proton generation and terahertz(THz) radiation in the laser pulse interaction with a thin-foil target. The maximum proton energy of ～2.3 Me V and an intense THz radiation were observed at the pulse duration of～30 fs. We also measured the proton beam and UV harmonics from a thin-foil target by changing the laser pulse duration. In the case of the ～500 fs, peaks of UV harmonics up to fourth order appeared. This unique combination of the multiple beams will provide useful applications such as pump-probe experiments.
