Approaching the “island of inversion”:P34

Yrast states in 34 P were investigated using the 18 O( 18 O,pn) reaction at energies of 20, 24, 25, 30, and 44 MeV at Florida State University and at Lawrence Berkeley National Laboratory. The level scheme was expanded, γ-ray angular distributions were measured, and lifetimes were inferred with the Doppler-shift attenuation method by detecting decay protons in coincidence with one or more γ rays. The results provide a clearer picture of the evolution of structure approaching the "Island of Inversion", particularly how the 1 and 2 particle-hole (ph) states fall in energy with increasing neutron number approaching inversion. However, the agreement of the lowest few states with pure sd shell model predictions shows that the level scheme of 34 P is not itself inverted. Rather, the accumulated evidence indicates that the 1-ph states start at 2.3 MeV. A good candidate for the lowest 2-ph state lies at 6236 keV, just below the neutron separation energy of 6291 keV.Shell model calculations made using a small modification of the WBP interaction reproduce the negative-parity, 1-ph states rather well.

“…The 6237-keV state was first reported in Ref. [9], where a 7 + stretched πf 7/2 ⊗ νf 7/2 configuration was proposed. The present work agrees with this spin-parity assignment, which also accounts for its relatively long lifetime.…”

“…Intruder negative-parity states with 1 particle -1 hole (1p-1h) character were previously reported to appear at about 2.3 MeV [5][6][7][8][9][10][11]. Hints already existed for possible 2p-2h positive-parity states at about 6.2 MeV [9][10][11]. The purpose of the present work was to obtain additional experimental information on the 1p-1h states to solidify tests of shell-model descriptions and to search for other possible configurations.…”

The available experimental information on 34 P has been greatly increased through the analysis of γ decays in coincidence with protons from the interaction of an 18 O beam at 24 MeV with an 18 O target. Light charged particles from the reaction were detected with Microball, and multiple γ-ray coincidences with Gammasphere. Many newly observed γ transitions have been identified and placed in the level scheme. Additionally, for most states, spins have been assigned based on measured γ-ray angular distributions while parities were inferred from lifetimes determined through Doppler-broadened line-shape analysis. Most of the states observed have been interpreted in terms of shell-model calculations using the WBP-a and SDPF-NR interactions having one particle in the 0f 7/2 or 1p 3/2 orbital. The two calculations agree almost equally well with the data resulting in root-mean-square differences of about 200 keV. However, a few high-lying states observed with long lifetimes challenge current calculations. Two of these may be associated with stretched πf 7/2 ⊗νf 7/2 states, but the calculations over-predict their energies by 2 -3 MeV. Furthermore, a newly observed long-lived 7919-keV state is established for which no explanation is available at present.
