Momentum dependence of spin polarization for beta emitting nuclei produced through charge exchange reaction at intermediate energy
In order to investigate the polarization process in charge exchange reactions, we observed the momentum and angular distribution as well as the nuclear polarization of a proton-rich beta-emitting nucleus, ^<28>P (I^π = 3^+, T_<1/2> = 270 msec), produced through the reaction ^<28>Si+^9Be at E = 100 MeV/u, by selecting the momentum and the ejection angle. An analysis by using double Gaussian functions resolved the observed momentum distribution into two reaction components, nucleon knockout and pick-up abrasion reactions, suggested in a previous study. The behavior of the observed angular distribution and nuclear polarization implies the influence of those two components. The momentum dependence of the observed nuclear polarization of ^<28>P could be consistently reproduced by a simple model, in which two reaction components are considered. The present study also shows that the charge exchange reaction at intermediate energy is a useful method to produce polarized beta-emitting nuclei, especially for proton-rich nuclei

電気工学科「大実験1」のための実験教材について : 鉄道模型のマイコン制御システム
applicationThis paper reports on the teaching material which is called "the system of railroad model controlled by Z80 micro-computer", for practical exercise of 4th grade in the department of electrical engineering. The students assemble electrical circuits and program the software for control the railroad model system. The students are able to learn independency, the sense of engineering and the ability for systematization by the practical exercise.departmental bulletin pape
