Abstract

An experimental study has been performed in order to study the nuclear structure in odd-odd In isotopes.

Low-lying nuclear energy levels in ¹¹⁰In and ¹¹²In were determined from de-excitation γ-rays produced with ¹⁰⁷Ag(α,nγ)¹¹⁰In, ¹⁰⁸Pd(⁶Li,4nγ)¹¹⁰In, ¹⁰⁹Ag(α,nγ)¹¹²In and ¹¹⁰Pd(⁶Li,4nγ)¹¹²In reactions. In addition, the ¹¹⁴In energy level structure was investigated with the ¹¹⁰Pd(⁷Li,3nγ)¹¹⁴In reaction. Properties of de-excitation γ-rays were determined from γ–γ coincidence, excitation, and angular distribution measurements conducted with Ge(Li) and Ge(intr.) γ-ray detectors.

A sequence of intraconnected levels in each of ^110,112,114In were assigned to the (��g_9/2^-1, ��h_11/2) configuration.

For the ^110,112,114In energy level schemes a model calculation has been performed using the pairing-plus-quadrupole model, which reproduced states of the (��g_9/2^-1, ��h_11/2) multiplets quite well. A value of the proton-neutron coupling constant χ_np of about 0.25 MeV was obtained for all three In isotopes.
