The (n _th, α)-reaction on⁹⁵Mo,¹²³Te and¹⁴⁵Nd

Abstract

Then _th,α)-reaction spectroscopical data are reported on⁹⁵Mo,¹²³Te and¹⁴⁵Nd (target nuclei). The⁹⁵Mo(n, α)⁹²Zr and¹²³Te(n, α)¹²⁰Sn reactions showed up two lines each corresponding to the ground state and the 1st excited state with a total cross section of 32 ub and 52 μb respectively. In the case of¹⁴⁵Nd(n, α)¹⁴²Ce, a transition only to the 1st excited state of¹⁴²Ce is present. It is shown that in the case of⁹⁵Mo,¹⁴⁵Nd and probably¹²³Te, most of the cross-section comes respectively from the 2⁺ possibly 4⁻, and 0 bound levels whose widths are determined to beΓ ^α=0.5 × 10⁻⁶ eV,Γ ^α=1.6×10⁻⁸ eV andΓ ^α=1.6 × 10⁻⁶ eV. The present results on these three nuclei, when combined with the existing data, are consistent with the calculated statistical model values.
