Abstract

Isotype shifts and hyperfine structure measurements for five transitions in natural dysprosium have been performed using a CW tunable dye laser and a collimated atomic beam. The consistency of experimental isotope shifts is tested and values of the change in rms radius of the nuclear charge distribution are calculated.

Isotope shift measurements in 555-833 nm wavelength region with FTS and electronic configuration assignments to the energy levels of neutral dysprosium atom

Citation Excerpt :
IS, the change in nuclear charge radii, δ<r2> and hfs A and B constants in 5 lines were measured using CW tunable dye laser and a collimated atomic beam technique [23]. SMS and FS factors have been evaluated using IS data observed in 31 spectral lines of Dy I by means of CW dye lasers with a collimated atomic beam [24]. J dependence of optical isotope shifts have been studied using high-resolution-atomic-beam measurements for the ground term 4f106s2, 5I8 of Dy I [25].
Precise spectroscopic measurements of isotope shift (IS), Δσ (¹⁶⁰Dy - ¹⁶⁴Dy) have been carried out in the 258 atomic emission lines of neutral dysprosium covering 555–833 nm wavelength region, of which IS data for 198 lines is being reported for the first time. The present measurements have contributed significantly to understanding the complex Dy I atomic structure, which enabled us to report the level isotope shift, ΔT (¹⁶⁰Dy - ¹⁶⁴Dy) for 100 even- parity and 82 odd- parity energy levels out of which ΔT (¹⁶⁰Dy - ¹⁶⁴Dy) values for 45 even- and 36 odd- parity levels are new. Earlier tentative assignments of 15 even levels to 4f⁹5d6s6p and 5 even- levels to 4f¹⁰6s6d configuration have been confirmed in the present study. New configuration assignments have been made to 10 even levels and also 5 each assigned to 4f⁹5d6s6p and 4f¹⁰6s6d configurations. The validity of 10 odd-parity energy levels theoretically assigned earlier to the mixed (4f⁹5d6s²+4f¹⁰6s6p+4f⁹5d²6s) configurations has been verified using newly derived experimental level isotope shifts, ΔT (¹⁶⁰Dy-¹⁶⁴Dy) values. Tentative assignments of 4f¹⁰5d6p configuration confirmed for the 5 odd levels lying between 35029.50 cm⁻¹ (J=8) - 37836.50 cm⁻¹ (J=9). The present investigations have led to the first identification of two almost pure levels of 4f¹⁰5d6p configuration at 35777.79 cm⁻¹ (J=8) and 36260.17 cm⁻¹ (J=9). The ΔT (¹⁶⁰Dy- ¹⁶⁴Dy) values for 2 levels of 4f¹⁰6s7p configuration have been evaluated by us for the first time, whose configuration assignments have been confirmed presently.

The experimental results published before February 2017 from the various reaction and decay studies leading to nuclides ¹⁵⁸Nd, ¹⁵⁸Pm, ¹⁵⁸Sm, ¹⁵⁸Eu, ¹⁵⁸Gd, ¹⁵⁸Tb, ¹⁵⁸Dy, ¹⁵⁸Ho, ¹⁵⁸Er, ¹⁵⁸Tm, ¹⁵⁸Yb, ¹⁵⁸Lu, ¹⁵⁸Hf, ¹⁵⁸Ta, ¹⁵⁸W in the A=158 mass chain have been reviewed. These data are summarized and presented, together with adopted level schemes and properties. Large sections of the mass chain are almost identical to the ones in the previous 2004He05 NDS publication by R.G. Helmer.

The experimental results from the various reaction and radioactive decay studies leading to nuclides in the A = 162 mass chain have been reviewed. These data are summarized and presented, together with adopted level schemes and properties, for the nuclides from Sm (Z = 62) through Os (Z = 76). This represents an update of the previous evaluation of the nuclear data on the A = 162 nuclides (1999He21).
