We have studied conduction-band (CB) electronic states of a typical valence-transition compound YbInCu$$_4$$ by means of temperature-dependent hard X-ray photoemission spectroscopy (HX-PES), soft X-ray absorption spectroscopy (XAS), and soft X-ray photoemission spectroscopy (SX-PES) of the valence band. We have described the valence transition in YbInCu$$_4$$ in terms of the charge transfer from the CB to Yb 4$$f$$ states.

Photodisintegration of $$^{80}$$Se; Implications for the s-process branching at $$^{79}$$Se

Photoneutron cross sections were measured for $$^{80}$$Se immediately above the neutron separation energy with quasimonochromatic $$gamma$$-ray beams to experimentally constrain the E1 $$gamma$$ strength function for $$^{79}$$Se. Two sets of the $$gamma$$ strength function and the level density that equally meet the experimental constraint predict largely different neutron capture cross sections for $$^{79}$$Se. Based on the Maxwell-averaged cross sections of the latest compilation complemented with the predicted cross sections for $$^{79}$$Se, we calculated $$sigma$$N values of the main s-process component using a phenomenological model and deduced empirical abundances of the weak s-process component.

Photoneutron cross sections for $$^{80}$$Se; Implications for the s-process thermometer

Makinaga, Ayano*; Utsunomiya, Hiroaki*; Kaihori, Takeshi*; Yamagata, Tamio*; Akimune, Hidetoshi*; Goriely, S.*; Toyokawa, Hiroyuki*; Matsumoto, Tetsuro*; Harano, Hideki*; Harada, Hideo; et al.

Photoneutron cross sections were measured for $$^{80}$$Se near the neutron threshold energy with quasi-monochromatic $$gamma$$ rays. Using the $$^{80}$$Se($$gamma$$,$$n$$) cross section as experimental constraints on the E1 $$gamma$$ strength function, we estimate the neutron capture rates for $$^{79}$$Se. The solar abundance ratio of s-only nuclides $$^{80}$$Kr and $$^{82}$$Kr are analyzed in terms of the s-process branching at $$^{79}$$Se within the local approximation. The corresponding temperature and neutron density regimes are discussed in the light of the s-process scenario in massive stars.
