论文摘要
我们介绍了Mo $ $ _ {1-x} $ re $ $ $ _ {X} $合金组合物在Mo $ $ _ {1-x} $ $ _ {1-x} $ resssions光谱实验的结果中，以临界浓度$ x_ {c1} $ x_ {c1} $ = 0.05和$ x__ {c2} $ x_ {c2} $ = 0.11。光电子显示了合金的恒定初始状态（CIS）光谱的额外共振（$ r3 $）以及两个与钼中观察到的共振（$ r1 $和$ r2 $）相似。所有共鸣都显示出类似Fano的线形状。共鸣的不对称参数$ q $ r1 $和$ r3 $的合金的不对称参数被观察到大且负数。我们的分析表明，大型负Q的起源与声子辅助带之间的循环间散射以及由于ETT而出现的狭窄带。
We present the results of resonant photoemission spectroscopy experiments on the Mo$_{1-x}$Re$_{x}$ alloy compositions spanning over two electronic topological transitions (ETT) at the critical concentrations $x_{C1}$ = 0.05 and $x_{C2}$ = 0.11. The photoelectrons show an additional resonance ($R3$) in the constant initial state (CIS) spectra of the alloys along with two resonances ($R1$ and $R2$) which are similar to those observed in molybdenum. All the resonances show Fano-like line shapes. The asymmetry parameter $q$ of the resonances $R1$ and $R3$ of the alloys is observed to be large and negative. Our analysis suggests that the origin of large negative q is associated with phonon assisted inter band scattering between the Mo-like states and the narrow band that appeared due to the ETT.
