Both effects are different in nature with respect to phase rigidity because of interference of non-time-reversed or time-reversed paths, respectively. Since their occurrence is largely governed by averaging effects, which depend on sample dimensions and the transport regime, we present a systematic study of flux-periodic oscillations of phase-pure zinc-blende GaAs/InAs core/shell nanowires as a function of gate voltage for samples with different contact separation lengths. Our analysis shows that with increasing contact separation length, averaging effects result in gradual reduction of h/e-periodic Aharonov-Bohm-type oscillations, while the h/2e-periodic Altshuler-Aronov-Spivak oscillations and its h/4e-periodic higher harmonics are enhanced. The additional phase rigidity seen in the h/3e-periodic oscillations is attributed to phase rigidity propagating from the neighbouring lower harmonics. Our tight-binding transport simulations on nanowires of different lengths which contain only a few scattering centers confirm the experimental observations regarding the different harmonics and their phase rigidity. Together, our experimental and simulation findings indicate quasi-ballistic transport with persistent Aharonov-Bohm-, and phase-rigid Altshuler-Aronov-Spivak-type oscillations despite few scattering centers.CC0 Waiver2606.10788https://arxiv.org/abs/2606.10788KWANT_Raw_data_2um.csvtext/csvKWANT_Raw_data_4um.csvtext/csvKWANT_Raw_data_600nm.csvtext/csvKWANT_Raw_data_S10_a.csvtext/csvKWANT_Raw_data_S10_b.csvtext/csvKWANT_Raw_data_S9_a.csvtext/csvKWANT_Raw_data_S9_b.csvtext/csvRaw_data_SampleA.csvtext/csvRaw_data_SampleB.csvtext/csvRaw_data_SampleC.csvtext/csvRaw_data_SampleD.csvtext/csvRaw_data_SampleE.csvtext/csv
