Lifetime measurements with improved precision in ^{30, 32}S and possible influence of large-scale clustering on the appearance of strongly deformed states

NUCLEAR REACTIONS ²⁸Si(³He, n)³⁰S, E=8 MeV; ²⁹Si(α, n)³²S, E=9 MeV; measured Eγ, Iγ, γγ-coin, level half-lives by Doppler-shift attenuation method (DSAM) using HORUS array of HPGe detectors at the FN Tandem accelerator facility of the University of Cologne. ^30,32S; deduced levels, J, π, relative population, B(E2), B(M1). Comparison with previous experimental results for level half-lives, and with two-band mixing calculation. Systematics of low-lying quadrupole states in ^{28,30,32,34,36,38}S. ³²S; discussed electromagnetic E2 transition strengths and quadrupole moment in terms of two doubly magic ¹⁶O clusters. ⁸⁰Zr; discussed superdeformed yrast band in terms of two ⁴⁰Ca clusters.
