Description
Low energy ion beams of around 10 MeV/nucleon is suitable to study the behavior of a nucleon on the surface of the nucleus. For the first part of my talk, I’ll present two experiments to study the single particle natures of 31Mg and 35Si which are located in the vicinity of the island of inversion through their isobaric analog resonances. The experiments were performed with RI beams of a few MeV/nucleon. I’ll also discuss a coming re-measurement of the isobaric analog resonances of 35Si as well as new experiments for heavy regions.
For the second part, I’ll introduce a new project. In the project, we aim to produce a large amount of “pure” hafnium isomer which has 16+ high spin and a half-life of 31 years. In the past experiments, the production cross sections of 176Yb(a, 2n)178m2Hf were measured and the chemical separation was performed to obtain samples of several % purity. In addition to these processes, we try to purify them by using the laser resonant ionization technique. The idea and the time schedule will be discussed.
