Abstract:
The cross-sections of (nat)Yb (n,x)(172,173) Tm, (174)Yb(n,p) (174) Tm, (174)Yb (n,α) (171)Er, (176)Yb(n,p) (176) Tm, (176)Yb(n,α)(173) Er, and (176) Yb(n,n')(176m)Yb have been measured at 14.6±0.3MeV neutron energy, among them two cross-sections (nat)Yb (n,x)(172,173)Tm are reported for the first time. These experimental cross-sections are compared with experimental data found in the literature, with evaluated nuclear data in JENDL-4.0 and TENDL-2010 libraries and with theoretically calculated values based on nuclear reaction modular codes EMPIRE-3.0 and TALYS-1.2.

Types of Radioactivity
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:
