A quasifree ($$p$$,$$pn$$) experiment was performed to study the structure of the Borromean nucleus $$^{17}$$B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for $$1s_{1/2}$$ and $$0d_{5/2}$$ orbitals, and a surprisingly small percentage of 9(2)% was determined for $$1s_{1/2}$$. Our finding of such a small $$1s_{1/2}$$ component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in $$^{17}$$B. The present work gives the smallest $$s$$- or $$p$$-orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of $$s$$ or $$p$$ orbitals is not a prerequisite for the occurrence of a neutron halo.

The author studied the effect of chemical compound for superconducting performance ($$J$$c) of iron-based superconductors. As a result, it was revealed that BaFe$$_{2}$$As$$_{2}$$ showed high Jc. And more, BaFe$$_{2}$$As$$_{2}$$ showed higer $$J$$c such as 32,000A/cm$$^{2}$$ (4.2K) by being applied of 120 MPa of hot isostatic pressure (HIP). Thus, higher $$J$$c performance could be achieved.

Pressure dependence of the irradiation-induced ferromagnetism in Fe-Ni invar alloys

Matsushima, Yasushi*; Sun, N. Q.*; Kanamitsu, Hiroaki*; Matsushita, Masafumi*; Iwase, Akihiro*; Chimi, Yasuhiro; Ishikawa, Norito; Kambara, Tadashi*; Ono, Fumihisa*

Pressure dependence of the irradiation-induced ferromagnetism recently found in Fe-Ni invar alloys was investigated under hydrostatic pressures up to 7.5 GPa. A rectangular sheet of Fe-30.2at% Ni invar alloy was irradiated with 80-MeV Xe ions. The range was much smaller than the thickness of the sample. The Curie temperature of the irradiated part increased by 63 K, and the absolute value of the pressure coefficient, d$$T$$$$_{rm c}$$/d$$p$$ was smaller than that of non-irradiated part. The relation $$p$$ $$approx$$ ($$T$$$$_{rm c0}$$ - $$T$$$$_{rm c}$$)$$^{n}$$ holds with n = 2 for both non-irradiated and irradiated part. The itinerant character was not so much modified by irradiation.
