Search for the 1/2⁺ intruder state in ³⁵P

NUCLEAR REACTIONS ²H(³⁶S, ³He), E=15.3 MeV/nucleon; measured E(³He), I(³He), σ(θ) using deuterated-plastic targets and HELIOS solenoidal spectrometer at the ATLAS-ANL facility. ³⁵P; deduced levels, J, π, spectroscopic factors, configurations, 0p0h waveform amplitude of the ³⁶S ground state, no candidate peak for 2p2h bandhead and a deformed intruder state in ³⁵P. Angular distribution data analyzed using PTOLEMY DWBA calculations with possible combinations of optical potentials. Comparison with previous experimental results. Systematics of experimental and shell model results for energies of 2p2h bandheads for the N=20 isotones: ³²Mg, ³³Al, ³⁴Si, ³⁵P, ³⁶S.
