Abstract

Excited states of $^{162} Er$ were populated in β decay and studied through γ-ray spectroscopy at TRIUMF ISAC to assess the nature of low-lying $K^{π} {= 0}^{+}$ instrinsic excitations. Improved measurements of the decay properties of the lowest $K^{π} {= 0}^{+}$ excitation suggest a β-vibrational nature for its structure. Data were also obtained ruling out the spin assignment of a previously assigned $K^{π} {= (0}_{3}^{+})$ excitation.
